I concur totally with Alisha's analysis, based on what you have posted, and your goal to reduce FICO in the short term. Get as many below 50% as you can, and make sure that at least half retain zero balances upon reporting date to the CRAs.
All of this is predicated only on FICO short-term scoring. Otherwise, from a purely financial viewpoint, pay down the higher balance/ interest rate cards first. Your Wells Fargo accounts are now costing you well over $200 a month just in interest, and are at over 90% util. Util on the CITI is also near 80%. I do not know the interest rates on any of the cards, so this is speculative.
FICO scores you on overall %util, on the separate %util of each card, and on the number of cards that report balances.
I dont want to sound negative, but will offer only one further observation. You are closing on your current house, and have $10K from that transaction available to pay off your CC debt, which is good from a FICO perspective. Congrats! But that equity will then be gone from your net liquid assets after paying off your CCs, and then when shopping for a new mortgage, will not be there in their review of your overall financial status. FICO scores do not secure mortgages or mortgage rate per se. They do a finacial review, and not just a FICO snapshot.
