It's ok Uky, we've all gone through it, now you're "experienced enough to still get yourself in trouble" like the rest of us.
I tried to do too many flashes before rebooting last night, did 2.0, gapps, new market, gb kb, and brother, ended up going back to my nandroid backup.
Most of the time you can do the rom, gapps, and a kernal together, all through recovery. I leave my phone hooked to my computer via usb, and in recovery, will enable USB storage. Then, I can take each file and change to "update.zip" and flash in turn.
It's afterwards that you do work, moving fonts, ringtones, apps, widgets, launchers, themes, boot animation, etc.
Black bar WILL NOT work in 2.0, the framework-res is not the same (my guess, yes, I tried it for the heck of it - boot loop on animation). I'm not sure who's porting it over, but JoelRX gave permission to go to 1.1.1, same holds here, it will appear sooner (than later), that's all I'm waiting for at the moment. For now, I just have ADW hide the bar.
