Update:
I originally installed CM7 (coming from LGB 0.9) using the all-in-one method and had a bunch of problems which I highlighted in some previous posts. Not sure what the root of the problem was, if I made a mistake or if something just didn't click between where I was and where I was headed. Eventually I bricked and had to SBF using RSD lite. I did that, regrouped and re-flashed my way back to CM7 build #19 and everything seems to be working really well. Fast, smooth and no glitches as of yet.
Just thought I would post this in case it might help anybody getting ready to make the move
