Hi there! I'm not one of the more experienced responders but I would say if there are accounts on your report that you know are in fact not yours you can dispute the directly with the bureas, if the company can not provide proof the debt is yours within 30 days then just expect those to be removed.
Now for the others that are valid and your collections you want contact the collection agency (I like to do this by email) offering a pay for delete. If they are small accounts I would pay them in full to delete. If they are large accounts offer a % for a deletion. If you can't get a PFD the first time, KEEP TRYING, even call them up. Never acknowledge the debt is yours, just simply say you want to settle for a delete. How old are the debts? By 7 years old they will fall off regardless if you paid or not, so that could possibly work in your favor.
I think the worse thing to do is make payment arrangements, it affects your credit score in a bad way with each monthly update. You want to knock them at once.
