Hello all

I am new to this board and love the fact that you guys are so interested in helping each other re: credit problems!
I have a few concerns that I am dying to have answered! I am looking to fix my credit asap, am looking to purchase a home in the next 6 months- 1 yr, and trying desperately to clean up my credit!!
I have several credit cards with low credit limits, a dozen or so store credit cards, an auto loan ~389/month, student loans ~546/month. The only derogatories I have on my credit is 1 late payment fm a store credit card in 2004, and 1 late on my student loan of 30-days back in Jan 06 because they left it out during consolidation. I also have an unpaid collection fm a utility company (electric co) back in 2006. I was looking to pay the collection but unsure whether it will increase my score to have it listed as a paid collection? They are not willing to delete it, because they said it is accurate information.
My current credit score (median) is 570.
What are your thoughts? How quickly will I be able to increase my credit score?
Also, will it hurt me to subscribe to a credit score watch or will it hurt me to monitor my credit?
