Hey Joe-
Is this the kind of thing you're looking for?

The template you posted actually looks pretty good (nice site too!).
I found a lot of drop down menu tutorials on Google so I'd think it wouldn't be too hard to find-unless I misunderstood what you were after.
I'm actually in the same boat too, I need to start getting on the CSS bandwagon. I use it for text formatting-which is really nice-but have yet to jump in the deep end of the pool for layout...! So much to learn...if you find some nice learning tools let us know too, hopefully we can all learn a little bit from each other.
Let me know if the tut helps! [righton]
