So stock rom, but rooted. You probably are at 160 dpi (unless you DID change it).
Sorry, I'm not much help with the stock rom. (I have no need or desire for stock.)
There is the Amazon app store to install apps too.
Then you should install dpi changer I linked to earlier and change your dpi to 160 to improve Market compatibility.
I find a lot of the free stuff I want isn't on Amazon.
You should update to a newer version of CM7, like 7.1 stable or 7.2 Mirage.
If you're not running off your sdcard, and the problem is only Market, you could open Rom Manager, download the latest gApps, create a backup (check the checkbox) when prompted and update that way.
The main fix for Market was the dpi change from 161 to 160, so no need to update if that's your only issue, but there were battery fixes in newer versions of CM7 as well.
On the other hand, if you're going to go to what much work, might as well update your rom too. http://androidforums.com/nookcolor-...dirty-upgrade-your-cm7-using-rom-manager.html
Updating thru Rom Manager only works if you replaced your stock rom with CM7 (not dual booting with a 2nd rom on the sdcard).
