Cyanogen 6.1.2 bootloop on rooted 2.2

I have read some about ADB, but unsure how to use it. I definitely managed to mess something up with how my PC reads the info from the Evo as it used to have Android 1.0 under device manager whenever plugged in, but now it's just indicating 'unknown device' going the RUU route tonight to try to get back to square one and start over.

Just so I'm clear, if I go the unrevoked route, all I need is the hboot driver download, and the unrevoked app itself?
