How many Joules of protection do you need in a surge suppressor?

A suppressor is rated in joules, and a suppressor is rated as to the amount of joules it can expend before it no longer can work to protect the circuit from the power surge.
I think you can find the answer to this question in Dehn-usa.com's "Lightning Protection Guide" or their "ABC's of Lightning". I put the link under the related links below.

How many joules are necessary for surge protection?
Surge protection and joule ratings for laptops determines its level of protection from electrical damage. When an external surge is detected, the protection equipment immediately blocks it.
What unit or measurement is used to describe the amount of work a surge suppressor can do before it stops protecting the circuit?
Depends on a type of protector. Some protectors work by absorbing energy. These might be rated in joules (pronounced 'jewel'). Are typically hundreds or a few thousand joules. Another protector for all types of surges works differently. It is measured in amps. For example a typically destructive surge (lightning is one example) might be 20,000 amps. So a 'whole house' protector is minimally 50,000 amps. Protector must not stop working. If properly sized, it only degrades. Protector that is grossly undersized stops working in a manner that violated the manufacturer's specifications. And that is a potential fire. A typically destructive surge can be hundred of thousands of joules. What does that do to the first type protector that must somehow absorb that energy? Two type protectors. One rated in joules. The other in amps.
What is a surge suppressor is designed to do?
When the power applied to a surge suppressor goes above the rated amount, a certain amount of that power diverted down a ground wire and dissipated. Surge suppressors wear out and should be replaced every two years. Answer: Any suppressor that degrades or 'wears out' in two or ten years is grossly undersized, is ineffective protection, and may even create a fire. Suppressors must be properly sized to not fail. For AC mains, a suppressor must connect short to earth (be adjacent) to what actually absorbs energy). Suppressors that make an effective (short) connection to earth are also rated at least 50,000 amps. To not fail even on direct lightning strikes. An effective suppressor connects transients (even tens of thousands of amps) to what harmlessly absorbs that energy: earth ground. A completely different suppressor adjacent to an appliance must somehow block or absorb that energy. These hundreds joule devices require frequent replacement when absorbing destructive surges that exceed tens of thousands of joules. Suppressors that need frequent replacement are undersized and are typically too far (many tens of feet) from earth. Completely different devices, called suppressors, last for decades and are located adjacent to earthing electrodes.
What unit of measure is used to describe the amount of work a surge suppressor can do before it stops protecting from electrical surge?
There are 3 items that can be used for surge suppression measurements. Most of the plug in strips use Joules as a measure but this can be very misleading. Joules is a measure of energy. Energy is current (amps) times voltage (volts) times time (seconds) or E=I*V*t. Voltage during a surge is critical in determining if downstream equipment is protected. So low voltage rating are important. Current during a surge is important as this is a measure of how many amps are flowing diverting the surge from the downstream loads. So high surge current rating are important. Time is not generally critical, but is determined by the characteristics of the surge. For standard surge testing, the time is identical for the same waveshape. So Joules appears useful at first glance because it incorporates voltage and current in one measure. However, one can increase the joule rating by increasing the voltage (bad) while decreasing the current (also bad). Joules can also be manipulated by using waveforms that are not standardly used in the industry. So rather than use Joules, it is much better to look at the voltage during a surge and the maximum surge current a product uses and ensure the testing is with a recognized standard surge waveform.
What type of lightning protection equipment do I need for my house I just purchases in Evansville, Indiana?
There are many types of lightning protection equipments such as grounding units, surge suppressors, and conductors. If you have electronic equipments, definitely get surge protectors.
What is a surge strip?
A surge strip is an electrical device that protects your valuable electronics from dangerous power surges, spikes, and overloads. However, many surge strips they have in production today does not support protection against power spurts.
What power company provides surge protection service for homes?
There are many Electric Utilities throughout the United States that offer Surge Protection to their customers or at the very least can recommend a reputable company to refer you to. You can usely find out this information by going to your Electric Utility's web site. Most Utilities will list their Surge Protection Programs under either "Products and Services" or "Member Services".
Is an amplifier protected by the fuse or breaker if a lightning strike has possibly hit the amplifier's circuit?
The result of a nearby lightning strike are unpredictable. If the strike affected the power line, resulting in a sudden spike of power, a fuse or breaker cannot possibly react quickly enough to save the amplifier. For that kind of protection you would need to install a surge suppression device on the power line. But even if you have a surge suppressor, understand that EMP (Electromagnetic Pulse) caused by a nearby lightning strike can cause damage to CMOS transistors even when the device is unplugged. Typically that doesn't happen, but it is possible. While the output transistors tend to be more robust, many of the low power circuits can be affected by lightning. Beyond a surge suppressor on any inputs and power lines, and the manufacturers shielding, there isn't much you can do.
