Socks are great to knit. I'm wearing the pair I've made right now. A good tutorial for beginner sock knitters is Silver's Sock Class.
The pattern is written for several different yarn weights, so you can make socks with worsted weight yarn on larger needles. It's written for DPNs, but she's going to make a tutorial using magic loop soon. DPNs look intimidating, and they're a bit awkward for the first few rounds, but you eventually get into the swing of it.
