Re: Couple extremely general linux questions...
Are you going to run the AMD64 version of SUSE? You would get better performance but only if it works properly. AMD64 ATI drivers are very young and will be more of a problem than the 32-bit which would increase the chance of things going wrong with Cedega or Wine.
You could install both 32-bit and 64-bit versions on separate partitions just in case 64-bit ATI drivers don't work.
