Congratulations!

Overclocking requires a kernel replacement...start here:

for these questions, I'd recommend Titanium Backup. The full version of Titanium allows you to FREEZE the app (make it non-executable) so it doesn't affect your ability to receive OTA upgrades (not that many rooters do that) AND backup your app data and save it when you're doing ROM upgrades.

Good luck and have fun!

Check out the sticky for rooting links. You'll have to install cwm, probably a rom, and a kernel if you so desire.

the easy way to do it is just using droidXcon's all-in-one package for odin
