You are sure to get some help here to start you on your way. Those 10 collections are not helping your scores, even if they aren't for anything major. If you have high balances on your credit cards, that's a score killer too.
You may want to post what cards you have the CL's and balances.
I would start off getting a copy of all three reports to see what you have that is negative.
Then start working on what you can handle to pay down, or offer PFD's, or just to make sure there are no errors somewhere.
If you need to ask a specific question about what's on your reports, you are sure to get the help you need here.
