Hi mschris, welcome to the forums.
If I were you, I would first start by addressing your CR. Make sure that all items that were to be IIB are listed properly. Then try working on your major baddies CO, collections. Try to PFD with the COs, DV the CAs (note your state's SOL before-hand). For positive credit building, you might want to attempt some secured cards, but I would work on the baddies first.
HTH
