I couldn't figure out the big deal of knitting a sock...until I finished my first one. I now have more dpns than you can imagine and a whole new stash of sock yarn.
I found a sock pattern on the web (sorry not at home and don't have the site) and just followed the directions step by step. AMAZING. That heel turned like silk off a spool and the gusset looked...well, like the picture.
If you're able, follow silver's sock tutorial (knitting in front of the computer) or some similar site with nice clear directions. It's much simpler than you'd expect. The dpns tend to be a little awkward until you get a way down on the leg. And I find that if I keep the ends of the needle I'm working on on top of the other needles, I don't have any ladder problems.
Good Luck. Have fun.
