untill now i have mostly just tried to get everything sounding nice in the multi-track stage and then mix it down to stereo and not touch the stereo track but lately i've decided that i need to try my hand at some home mastering, my home recordings usually sound a few decibles lower than other cds i listen to, i'm assuming i'd use some compression to bring it up?
If you just need some decibels I wouldn't call this 'mastering'

, but anyway,
a compressor/limiter is your friend.

what is a good starting point for that? also, how much eq tweaking do you all do to your stereo mix? i've always been worried that if i try to start eq-ing i'll end up overdoing it and ruining the sound. sorry for the amature questions.
Now we're coming to real mastering questions, and the answer is 'that
depends'.
Each song is different, therefore there exist no general
eq/compressor/whatever settings.
First advice: let a mastering engineer do this
If you want to do this on your own and you (most probably) don't own a
mastering studio with dedicated mastering monitors, my advice is to listen to
your songs on as much different systems as possible (computer, boom box,
car, home stereo/hifi, friends/parents/whatever stereo) in as much different
rooms as possbile.
Make notes for each song on each system.
Try to find out common problems (track 3 sounds too harsh on 7 of 10
systems, track 6 lacks bass on 5 of 10 systems) and address these.
Start over again

until all tracks are playing fine on a maximum number
of systems.
Sometimes a track seems to be unfixable. If so you most probably have to
go back to the mixing stage to fix it there.
It's a lot of work, but when you've succesfully done this a couple of times
you'll learn more and more how a track should sound on your mixing monitors
before testing it on all the other systems, so the number of turnarounds will
become less and less each time.
Your songs will still not sound as good as professional mastered songs, but
they'll be closer to the 'real thing'.
Good luck.
