Well, to swear in church, this is where the advantage of digital comes in to play, because you can test and test and test until you get it right, instantly.
I learned to use my studio gear myself trough a couple of basic books, time, willing friends and trial and error.
After a few years now. I know what to expect, but I still don't shoot studio photos with film unless I double-check everything with my 1ds MK II first, if the light or exposure is wrong, it's poop in - poop out and a waste of film, time and money.
I've never really seen any great learning videos on studio lighting to be honest. There are many, but this is like cooking; You know what you want, you need to learn how to get there, sort of.
The only really great and inspiring video I'v seen on studio-stuff is Thorsten Ott's tutorials on light and equipment.
He provides schematics and explanations along the way and the final result is really something that makes you want to start shooting straight away.

I do think though, that if you've never really used studio lights before, even Thorstens video's can be a little more on the advanced side.
Still highly reccomended! (here's a preview):

I also have the DVD's from Dean Collins, but they are very technical and to be honest, I didn't get much benefit from them at the time I was viewing them, may be different now though.
Also, buy a good book, for example this one (I own it myself):
Dead Link Removed
Study it and then check out Thorsten's video.
Still, you need to practise, a lot, to get a good feel for how things work together and what kind of effect various modifiers make.
