I'd use the money to pay the $1300 CC. Utilization is killing your score.
How does it list on your CR? Does it say "charge-off"? How old is it?
If it is an old card, I'd pay right away without using a PFD. Deleting this account could kill your history. If it is a new card, then I'd set up a PFD with the CC. If it says "Charge-off", then negotiate a PFD if a new acct. If it doesn't say "charged-off", it might say closed by credit grantor, I'd mail payment ASAP in full.
