Credit Repair....please Help

I have a few questions about my credit report. Any information would be greatly appreciated...

1. I filled Bankruptcy Ch-13 in 09/2000,
three weeks later I realized how stupid that was so I wrote a letter to the bankruptcy court and had it canceled.
When I pulled my credit report three weeks ago the bankruptcy was the first thing that was on there. Is this going to stay on my credit report for seven years or can I have it removed?...I am currently in the middle of disputing it, what should I expect?

2. I tried to order my credit score from equifax, but when I did they said I haven't had an active account in six months so a score can't be generated.What exactly does this mean? This is probably a bad thing right?

3. One of my creditors have been pulling my credit report twice a month ever since I cancelled my bankruptcy...this is allso hurting my credit right? Is there anything I can do about this?

4. I currently have thirteen items on my credit report that have a 0 balance and say "pays as agreed", four "charge off's" , nine collection accounts and a BK CP-13
Is it possible for me to come out of this with a decent credit score? I am currently disputing all the negative things and plan to contact any creditors left negetive after the dispute. Any advice would help out alot.
Thanks,
