Everything went well!
One small hangup that may be helpful to others - when the instructions on the teamovercome page say to "sync with kies at least once" - you don't have to transfer data or anything, it just means have kies open, connect the tab, and make sure the drivers install successfully.
The bootloader patch went well - my device only allows installing signed firmwares, but that's fine.
Ran with teamovercome 4.1.0 for a while, but decided since I don't have a dock with HDMI for it yet that I'd give humberos a try.
Very simple install - copied the three zips to internal storage, flashed with CWM as instructed, boom.
Very nice guys, thanks for all of your help!
