I've decided that I need to try making socks, so I'm getting ready to place an order for some fixed circular needles from Knit Picks. I thought I'd get some inexpensive yarn to practice with, so I'm going to get some of their Essential Sock Yarn. I'm sure somebody here has used this yarn, and I was just wondering if it was good yarn to work with, and can I get a pair of socks out of one ball or will I have to buy more?
Also, I was going to order needles in sizes 1, 2, and 3. Size 1 has two sizes, 2.25 mm and 2.50 mm, and size 2 also has two sizes, 2.75 mm and 3.0 mm. So, what's the difference, other than .25 mm? Which ones should I buy? Does it really make any difference? Any guidance would be helpful here.

I tend to be a tight knitter, if that makes any difference.
Thanks in advance for any help.
