For "around-the-house" socks, you should be fine using worsted or light worsted (Caron SS).
I just made a pair of socks using this video series: (note: this is just the first video in a series of 6) http://www.youtube.com/watch?v=1wSFaGpmVSw
She explains things really well (and she follows Stephanie Pearl-McPhee's sock recipe to a T); however, you're also supposed to buy her sock pattern to go with the video. It's $8 if you want to go that route.
BUT, she gives you almost all the information you need to make the sock in the videos. The only part that I couldn't understand from the videos was turning the heel. For that, I used the instructions from this pattern (with a few minor adjustments, like what side to start and stop on): http://www.ravelry.com/patterns/library/easy-peasy-socks-for-first-timers.
By the way, this pattern and the videos are for worsted weight yarn. You might want to use the written pattern to make sure you get the right gauge.
If that combination doesn't appeal to you, look up sock patterns in aran or worsted weight yarn on Ravelry. Be sure to choose your yarn weight in the category on the left.
