go to a site like emulator-zone.com and download one
The android market has a number of good emulators, including fpse (playstation). The slide.me market has all the -droid emulators (gearoid, gameboid, psx4droid, etc.) There are some other emulators too, like a great N64 one by paulscode. You will need to google for this.
Yes.

It is really hard to say that there is a master emulating software out there but there are some good ones. The only downside to PS2 emulators is that you need an VERY good PC to play them because for some reason it sucks up your processor useage pretty good. So it's not so much the software (Although that does help) but more about your own personal computer. If you have an older computer i suggest upgrading your processor and RAM (if you don't have more than 1gb.) and possibly a graphics card to lessen the load on the CPU. I can't really link you to any of the emulators but I'm sure you can find one your self pretty easy.
no i have a lot of games for a good share of emulators for different systems.
Yes, it would be a good idea. Unfortunately, with the availability of emulators being pretty much free I don't think there would be much of a market for it. Sorry.
You can find many great websites that have downloads of many emulators (including the DS) and they usually update them so you don't have to worry about getting the wrong, old model. The emulator-zone is a good place for your emulator needs.
Yes, PlayStation 3 is a electrical good, because it uses a power.
you cannot reinstall games on the ps3 because once the ps3 has installed the game its on the system for good.
