I found a 3g iphone at a yard-sale for $20. To my surprise it had v. 2.2.1 and BB 02.30.03. I want to know how to unlock the phone (most important) and upgrade it if I can.

Wow, $20, nice find! You can use Sn0wbreeze (Windows) or PwnageTool (Mac) to make a custom jailbroken 4.2.1 firmware to upgrade your phone without upgrading the baseband. Then run Ultrasn0w to unlock.
4.2.1 is the newest firmware a 3G can run.

I would actually restore it to 3.1.3 first to update the baseband to 5.12.01. Then you can either stay at 3.1.3 and jailbreak with redsnow 0.9.4 and unlock with ultrasnow or you can use pwnage tool or snowbreeze to make a custom 4.2.1 and restore to that. You will need a higher baseband then what you have for it to work with the newer firmwares but you dont want a baseband that is too high which ultrasnow will not be able to unlock.
Basically stay away from restoring to a regular 4.1 or 4.2.1 firmware.
