To boot into CWM Recovery simply turn the device on and when you see [SAFE SYSTEM: DISABLED] press the menu key and you will enter CWM Recovery.
Always make a Nandroid back-up before flashing Roms or anything else. I will update if i decide im brave enough to try a rom.
2/12/12 Update : I did a Nandroid backup while safe system was disabled, I did not try to flash it in either mode. I myself am holding out until I can get an SBF file or another means of restoring original firmware.
2/15/12 Update : I enabled safe system, after enabling safe system the recovery backs up original rom and starts safe system. After safe system is enabled if we had a rom to flash we would then do that. And phone would boot the same way with the option to enter recovery or continue since there isnt a rom yet you would boot recovery and go to advanced > disable safe strap and it will remove the alternative recovery and boot normally. You must then reinstall recovery the same way as before
