No, it is not a tube amp, it is a solid state amp.

Standby is a usefull feature on a tube amp, as it keeps the tubes warm and saturated, but cuts off the output to the speaker. Standby should be used when on a break, but not as a true "on/off" switch.

A Crate Electra guitar is an electric guitar that usually comes as a beginner's starter package from Crate. Don't know if they are still available as a new item, but i know that when they were the cost was between $150-$280 (U.S.) depending on what was included in the package and the wattage of the included amp. If you can find a used one it should be about $50 (U.S.) for just the guitar and in good condition.
Crate amps can be found on the website Crate Amps. Guitar Center and Musicians Friend also sell crate amps. For a more economical priced amp, eBay has a selection of crate amps for auction.
between $250 and $300.
It all depends what sound you are looking for, and how much money you are willing to spend. If you can afford a good tube amp, then go for it, because you are going to get much much better sound from a tube amplifier.
No.
Yes
Sequential Cascading Gain .. just another way of saying distortion.
Yes, you definitely can. Many bass amps are tube.
The best guitar tube amp is debatable and will vary by people's own tastes. However, you if you are looking for the best value, you will want to try Bugera amps.
The main reason people buy a tube amp is for the power tube distortion. A lot of people look for lower wattage amp (between 1.5 and 15 WATTS) so when they turn it up louder they get the natural tube "mud" on the sound. If your amp is beginning to distort or become muddy at higher volumes then you are pushing your power tubes. This will not damage the amp but it may damage your sound. I recommend buying a new amp with a higher wattage rating. This extra "head room" will give you the ability to play louder without distorting.
The technical specifications of a keyboard amp will vary depending on the brand and size of the amp. Some of the many brands of keyboard amps are Crate, Roland, Traynor and Ultratone. The specifications can be found on the sites that sell these amps or on the company websites.

That depends on how loud your drummer plays :-) It also depends on what type of amp you are using. A Tube/valve amp will put out a fair bit more volume/sound pressure than a solid state amp. e.g. it's not uncommon to hear a 30Watt tube amp sounding louder than a 100Watt Solid State amp sitting next to it. Finally another thing to add into the equation if you play a tube amp is how you want to play it. Some guitarists want that power tube break up distortion sound in which case they really are cranking the power section of the amp. Even a 10Watt tube amp being totally cranked is going to sound really loud but ultimately you want something that will at least fill the venue without enough sound pressure. Therefore standing close to a cranked 10Watt tube amp is going to sound deafeningly loud but at the back of a filled pub it's not going to cut it simply because it's not putting enough sound pressure through the speakers Having said all that at a typical small venue gig (like a pub or bar) with an average volume drummer you might get away with an 20W tube amp or a 50Watt Solid State amp but to give yourself some headroom (i.e. not have to run the volume near max) probably a 30-50Watts tube amp or 80-100W solid state would be a safer bet.
