RECOVERY FIX FOR THOSE WHO CANT FLASH ROMS (THIS IS ALREADY INCLUDED IN THE PACKAGE ABOVE AND IS FOR PEOPLE WHO ALREADY HAVE ROOTED OR HAVE A BROKEN RECOVERY):

Maybe that will help. I recogmend you flash a couple sense based roms and get comfortable first before you jump to open source land. To be honest everytime I go to ASOP or Cmod I run into things that dont work for me and I end up back at Sense. I can totally see your pain, if you havent been around long the methods to root are extremely confusing (helll just look through the link i posted above), which version, which hardware, its insane. Honestly I just went to XDA to the unrevoked link and followed their method to the letter and had great success.
Edit: Confirmed it helped this person.
