I'm a big fan of socks! There are so many techniques out there (dpns, toe-up, cuff down, Magic loop, 2 circs, 2 at a time...) you can't get bored! I think the anthropologie-inspired capelet is also a great idea, and it's been on my list for a while but I have too many WIPs right now.
I think in a way the best thing for you to do is to find a pattern you absolutely love, and just go for it!
If you can knit, purl, cast on, bind off, increase and decrease, you can pretty much make what you want. If you need help, no worries, KH is there for you!
