I would advise to make a spreadsheet with all of your accounts-
Create a plan to pay off revolving debt
Attack the derog items- starting with the biggest, baddest ones and the most recent ones, focus on one at a time.
Work back in time one derog at a time-
This will give you the best FICO results- and hlp keep you motovated and keep you from becoming overwelmed.
Other advice:
When disputing know the Best and worse posible outcomes - you should know what the results should be prior to disputing.
Save "low hanging fruit" for after the repair is completed.
Be aware of anything that is not reporting- as when your scores start going up colletions come out of the closet.
