Errm, you're making a mountain out of a molehill. This is all very simple, whether you use Radeons or Geforces. (￣ェ￣;)
1) Definitely use the newest drivers available, unless they have some serious problem with your specific card. I usually don't update unless I happen to think about it, but you generally want the newest drivers available.
2) Installing drivers is piss-easy, just run the installer. Removing them is just as easy; go to your add/remove programs (programs and features, rather) dialog and remove them. Upgrading is just as simple -- remove your old driver, restart, install the new driver, restart as prompted. Done. The days of driver upgrades being a huge pain in the butt is long gone; if you have troubles, you're doing it wrong. （￣～￣;）
3) You probably don't need to mess with your driver after installation unless you're trying to fix some kind of problem. Best to leave things at default settings. Stuff "just works" 99% of the time, even on Radeons. (well, maybe 98% of the time.) (￣ω￣;)
Seriously, it's no big deal.
