You don't need them for a propane grill. I put them in though because I like the flavor it adds to what I am cooking.
Lava rocks are made of basalt, which is made from andesite and dacite. Basalt will come in a wide variety of textures as well as colors.
it is fine to use propane all winter; propane freezes at -187 C (thats 187 degrees below zero, Celcius) which is far lower that any temperature ever recorded in nature
That is going to be up to personal preference. Propane tends to have a hotter flame than natural gas. Propane requires tanks, while natural gas can be piped in from your home service. I prefer natural gas, as grilling slow gives me better results than fast.
Propane Uses: BBQ Fuel Part of LPG car fuel Used in production of petrochemicals Used in some flamethrowers Hot Air Balloon Fuel Can be used to power airsoft/paintball guns Liquid propane is used for movie stunts to cause explosions Butane Uses: Cooking/Camping fuel Part of LPG car fuel Used in production of petrochemicals Cigarette lighter fuel Propellent for aerosols
I recently built a food smoker out of a food grade barrel and wanted to heat it using propane. After researching the Internet and pricing out parts, I found the easiest way to get the propane burner was to buy a cheap old gas grill off of Craigslist and salvage the parts I wanted. Basically all you need to do is take the fittings off of the grill and find a way to attach them to the inside of your barrel or smoker. I then bent up a small wire rack that holds a pan for my smoking chips, with the burners right underneath it. I've been able to get my 55 gallon drum up to 300 degrees or more. Long story short, they're hard to build, easy to salvage.
No, you do not, but you can if you want to!

Propane
There is only one type of propane that can be used for your BBQ. If you go to any store that sells propane for BBQs you will be able to purchase a tank of propane. However since this is the first time you will be connecting your BBQ to a propane tank you have to make sure that you have the right fittings and hose to connect to the tank.
Some stores that sell bbq propane grills are: http://www.bbqs.com/, http://www.grillsdirect.com/ and www.thebbqshop.com Those are all great and trustworthy.

Propane, LPG, or natural gas (methane)
You can find the instruction manual for your bbq propane grill at the manufacturer's website. You can the company's name on the label on the grill and they probably have an 800-number listed as well, which you can call for immediate help.
Flavor. Or the lack of, compared to charcoal or hardwood.
Type your answer here... there are around 91,600 BTUs in a gallon of propane. The standard BBQ sized bottle of propane contains 11 pounds of propane. Propane weighs about 4.2 pounds per gallon, so that 11 pounds of propane is about 2.5 gallons in its liquid state. That means there is 91,600 BTUs/Gal times 2.5 gallons so a BBQ sized tank of propane contains about 2.3 million BTUs. If your BBQ has a 50,000 BTU burner, on high heat, it will last a bit over 4 and half hours of run time.
