I fixed the adminlog one in the latest beta (836, I hate how the build log is so slow)
The key errors are ok, that's the format phpmyadmin had dumped them out so I'm assuming they're ok.
What MySQL version are you running? And is innodb enabled? Can you do a dump of structure from phpmyadmin and attach it to your post?
EDit: I just checked, the install.sql didn't update. grr. But the other errors you're getting are strange.
