ok try this, in rom manager go to the bottom where it says flash alternate recovery, click that and then after that finishes try to flash the clockwork recovery again and then power off again and try booting into recovery.
You don't have to backup current rom again because you already have a recent one to restore if something does go wrong, but yes do wipe data and cache and go ahead and try again.
ok well log into your gmail account from your comp and google talk is part of gmail. If you don't mind it will be a lot easier to type back and forth through gtalk. What is your gmail name?
