Repairing Personal Credit

Hello. I have bad credit, due to personal bankruptcy of a couple years ago. I am trying to decide how I can improve my credit rating. One idea is to get a secured installment loan at my credit union. They require one to open a cd, with a minimum deposit of $2000, but they dont charge a loan fee like the banks ($100 or more). Would this significantly improve my credit rating? My plan would be to pay it off sooner than needed.

Also, if I get a secured credit card, and pay a bit over the minimum reqired (perhaps 20%), would that be a big help?

Any suggestions?
