Don't worry guys, I got this one! I'm a pro after this weekend.
If bootlooping after SBFing to stock:
- Pull Battery
- hold volume down and power
- arrow down to android recovery
- press volume up
- you're going to get an exclamation like it failed, hit both volume up and down, it will go to stock adroid recovery
- Once you're in recovery, do a factory reset. It'll take a bit, but it should load now
- Once you're back on stock, re-root with the one-click
- download ROM Manager from the market
- From rom manager, flash the current CWM Recovery
- Download Joker's Recovery v3 and save to your SD card
- reboot into recovery again
- install from SDCARD - Joker's recovery
- Reboot Recovery again, from the CWM Recovery options, this will boot you into Joker's Recovery
- Do a full wipe (system, data, cache)
- Flash 3.1 which can be found a few posts back
- Once you've flashed 3.1 and booted the phone, reboot into recovery again
- flash 5.0 or 5.1 twice (I did it without wipe), without custom options
- flash GAPPS
- reboot the phone
- Should have coverage now

And actually, I hadn't practiced what I preached above until now. Just had a chance to flash 3.1, and I can tell you I followed the steps above and it worked. Thanks to Fanboy Hunter, Acvice, and anyone else I forgot to mention. Your help has been appreciated. I am now back up and running 5.0 WITH mobile network and 3G. I've learned a lot the last TEN DAYS. Man, what a battle.
