I think HSM, probably. I would also suggest you see if you can find a few books. My all-time favorite lathe book is "The Amateur's Lathe," By L.H. Sparey. It's English and may be hard to find, but I think it's still in print.
Closer to home, get South Bend's "How to Run a Lathe" from Lindsay Publications. They have a lot of other machining books as well. I've personally found that I don't get a lot out of their older machining book reprints, but you may find some of them interesting.
If you can find a local club in your area, or fellow metalworker (preferably one who knows more than you do), join or make the connection. When I started out I was totally on my own, and it all got a WHOLE lot easier when I hooked up with some other people and could learn from them.
