First welcome to MobileRead.
I would start over again:
1. flash firmware 2.0.2 <- A lot of problems can occur if you don't get your firmware back to the original 2.0.2
2. flash repack 2.0.3
3. get GMail working
4. get Android Market working: Are you saying that you don't have market on your emulator? did you follow the steps on this site?

5. Get a2sd working
Hope that will get you going.
Cheers
