Where to begin to correct my POOR credit rating of 540

          I came across your website and for a short moment I beamed with happiness, but then I realized I do not know where to begin to correct my POOR credit score rating of 540. I’m ashamed and confused all at the same time about my credit report score. I have obtained all four credit reports from Experian, Equifax, TransUnion, and Choicepoint. My credit report summary is listed as the following
Real Estate: 0
Revolving Accounts: 7                        Carrying a Balance: $4,216
Installment Accounts: 30                   Carrying a Balance: $75,759
Other Accounts: 4                              Carrying a Balance: $603
Collection Accounts: 11                     Carrying a Balance: $2,495
 
Total Account: $83,073
 
1.)    I have so many duplicate accounts on my credit report;  how do I get them to remove this off my report.
2.)    I have accounts with differences in Open and Closed status; ex. Experian will say its Closed and TransUnion will say it’s Open.
3.)    I have Seriously Past Due accounts from 1999 – that are still listed on my credit report. How can I take it off my credit report?
4.)    I have over 16 Student Loan accounts that say “Account transferred to another office”. Can I take this off my credit report?
5.)    I have another set of student loan debt that states, “Too new to rate” / “Unrated or bankruptcy”. Is this a negative statement for my credit report?
6.)    How do I stop companies from inquiring in on my credit report?
 
I have completed my BS, MS and MBA with the $75,759 in debt. I am also considering going for my PhD In Education, however I would like to settle all of these credit report & FICO score issues before continuing with my education.  I have only 2  short-term goals within a 2 year range(1) build credit report and FICO score, (2) Purchase a house within 2 years. My five year goal is to be Debt Free excluding my future mortgage.

you should dispute anything inaccurate, duplicate old or fishy
do it in disputes of 4 per dispute or less
 
transferred or sold should not hurt your credit unless they show up as being late
but
dispute them also
 
creditors cannot legally inquire over and over
threaten suit
