Unhappy careless changes to /usr permissions, /usr/share for USB, ALSA, wireless et al

Hello everybody, I'll try to keep this short and topical. I'm looking for someone to point me in the right direction, not for help diagnosing the problem, necessarily.
I was careless with /usr and /usr/share and made some recursive changes with chmod and chgrp: adding the setuid and setgid bits to /usr, changed /usr group to adm, then making /usr/share writable by group.
This, of course, made sudo and mdm fail. I fixed those, but now I have problems with various device drivers: If the login session is not the root user then ALSA, USB, my wireless card, and the battery monitors (portable) aren't working.
Right now, almost everything in /usr/share, /usr/lib, and /usr/src is rwxr-xr-x root root (trying to get it to work again), but as that didn't fix the drivers or whatever I now am going through and examining the permissions from the live installer copy.

Anyway, so I will continue doing this as an educational exercise for myself. What I am curious to know is whether it is possible that the problem has spread from /usr, perhaps causing some changes in /etc during boot when it found undesirable permissions modes.
Er, I'm not completely new to Linux but I have some gaps in my knowledge, such as I yet don't even know where I can view my boot log though I maybe will have found that information by the time you read this.

There's little that I can post online, because it would probably be a huge ls -lAR dump.

Thank you for taking the interest in helping, et c.

Have a gander at /var/log/boot.log
