I agree with learning how to make socks with DPNs. Using them makes sense out of the construction.
Silver's sock tutorial is great because she puts the number of stitches you'll need to make the heel flap and turn on 2 needles so you don't need to mess with moving stitches to other needles, which complicates things for the novice.
I, personally, use 3 DPNs - needles 1 and 3 holding the "heel" stitches and needle 2 holding the "instep" stitches.
The trick to DPNs is knowing how to hold them, obviously. Just make sure that the right side of each needle is over the top of the left side of the needle before it. So you're always working over the needles not underneath them. Did that make sense?
Don't be afraid, jump right in. You'll become addicted.
