You must immediately go to your LYS for a second set of needles.
More seriously, it's always good to have a second set because they fall in between the sofa cushions or otherwise get lost. I also have found my size 0 handy for repairs even tho' I've never made socks with an 0 needle. If you continue to do socks, it's nice to have a second set so you can work on both socks, alternating, at the same time.
I think you'll enjoy socks. They are small to carry around and provide a change of knitting as you go through the process. Let us know how it goes for you.
