Well there is no reason to go back to stock to flash another ROM - just choose a ROM and we can help you get it flashed successfully
Bugless Beast v.5 is a pain in the butt to install correctly. It has NO business being on ROM Manager!
Having said that, restore your back up (if you have one) and then flash another ROM. LFY, Sapphire, Simply Stunning, CyanogenMod 6.1 RC2, and several others are a very good choice for new ROMers as well as just plain new rooters.
Please note, each of these ROMs require the Google app pack to be installed separately. This isn't a big deal with the possible exception of Sapphire, which IIRC requires you to install the app pack before rebooting the ROM the first time. With Clockwork this shouldn't be an issue, but be aware it's a possibility.
