Get bad credit removed and good credit added to my credit report

Is there anything that I can due to remove Paid in settlement/Accont charged off. I have three Negative items on my credit report. They were all opened in 1999 and paid off some years later, is there anything that I can do write letters etc.
----------------------
Probably not
you can dispute them as not yours or not reported correctly and hope.
Best to get new good credit and go on
-------------------------
I have established new good credit, but the bad old paided and charged off credit is probably what's causing my credit score to be around 615. All of my new accounts are in good standards, paid and never late. and I beleive in the state of Maryland, it takes 7 years from the time of the last activity for them to be removed.

What if I send in statements of why this had to happen, will that help my score?
--------------------------------
Lower credit limit ratios to less than 80%
are the acounts one year old yet?
2 years is where the big credit score damage is done.
------------------------
All old paid off accounts were opened in 1999, there are three of them, they have been paid off anywhere from 2 to 4 years

All new accounts are in very good standards. I only have one that is not a year old all other accounts are a year old.
-----------------------
The 99 accounts are not hurting you much
keep trucking.

Thanks, I guess what I need to know is what do I need to do to get my credit score up. Pay down my credit cards, which are between 80% to 100%, and that is only two accounts, but I do have a loan with my credit Union, which is around 5,000, other than that there is nothing else.
--------------------
pay them down yes
below 80%
