Depends on if you want it tethered or untethered. (Tethered means that when you shut down, it will boot up to the original Apple software. Untethered is permanent unless you reset the iPod)
I recommend Greenpois0n (with a zero for the second O) for untethered and Redsn0w for tethered. Both are trusted jailbreaks that are nearly always successful.
Jailbreaking an iDevice not only matters the generation, but more importantly wish version iOS your device has. FOr a 3rd Gen iPod Touch, the iOS is from 4.2.1 to 5.1.1 and all iOS firmwares in that range are jailbreakable. It all is user preference on which you would wish to use. Just make sure the jailbreaking software matches the version iOS you are trying to jailbreak.
Popular jailbreaking software: greenp0ison, redsn0w, blackra1n.

Yes, the jailbreak will be lost. When you upgrade your iPod Touch software, it is completely reinstalling the software used to run it. When you jailbreak an iPod Touch, you are only jailbreaking the software, not the actual iPod.
Updating the iPod Touch software erases the jailbreak. You can update, but it will erase your jailbreak.
It depends on what software your ipod is running.
Redsn0w.
Currently, a 3rd generation iPod Touch cannot be jailbroken. The 3rd generation iPod Touch has a built-in firewall of sorts, and prevents jailbreaking. This was a measure taken by Apple to ensure that no one can jailbreak the iPod Touch. However, there is a jailbreak software currently being beta-tested for the 3rd generation iPod Touch.
