And just in case your mind hasn't been boggled yet, below is a great tutorial on how to knit socks from the cuff down. There are 6 or 7 of these videos, and you pretty much don't need to buy the pattern because you can figure out everything (except turning the heel) from what she tells you in the videos. These are done in worsted weight, by the way, so if you successfully complete your first pair in regular sock-weight yarn, you might not even need to watch these.
HOWEVER, what she teaches is a basic "sock formula," so it's handy to know. If you do decide to go this route, holler when you get to the turning the heel part, and I can refer you to the pattern I used to complete it.
Meanwhile, here's the first video:
