I just came across the thread in which you posted your panic log, and I would recommend that you downgrade for now (until the fix comes out). To downgrade, download build 4128 and run the uninstaller that came with the installer for build 4560. Restart and install build 4128. Then restart again. Hopefully you will be able to then use Parallels again without crashes.
After reading that there is going to be a new build to fix a problem that causes kernel panics, you might want to wait just a bit longer. I haven't had any myself, but since you are worried about the possibility of being one of the few that has problems, waiting just a little longer wouldn't be a bad idea.
