Dude...sounds like you just made it hard. Its actually quite simple.
Pull battery, put in download mode.
Odin the Verizon firmware with atlas.pit and repartition checked.
let it boot, then shut it back down and go back into download mode and Odin the fixed recovery for CM7. Then flash MIUI and profit.
It shouldn't take but about 15 minutes out so for the whole process
