Theme without ROM

[andriakaye#AC]

I searched the forum and couldn't find what I was looking for, so I'm sorry in advance if this has already been asked.

I am having a hell of a time trying to play nice with ROMs. I just did the cyanogen mod release using ROM manager which i loved, but then my market was all jacked up and i couldn't get all the apps i previously had backed up. When i searched for them in the market, they were just completely gone. so I went back to my nandroid back up and am back at square one. I love the idea of being able to use a ROM and themes that work with the ROMs, but if it's going to cause issues with my apps then I'm not dealing with it. So, that leads me to the real point of my post...

Prior to ever trying to install a ROM I installed a theme that just worked on stock froyo without any specific ROM. I believe it was one of the dark edge themes. I am wondering if there is an easy way to find more of those themes that don't require specific roms and can be loaded straight to my device with stock froyo? If not, any hints on how to resolve the issues I'm having with my apps after installing a ROM that requires clearing data/cache?

Thanks a million for any support and input. I'm a real android noob here
