PET bottles will work for a while but if you are serious about brewing, invest in a kegging system. You'll be able to do so much more and I think the result is better tasting cider. I've always found that cider yeastie-beasties don't need much in the nutrient department. They are voracious little buggers right out of the pack.
Depending on what you want from your cider (sweet vs. dry), you'll have to make a couple of batches to get your start and stop point set so you hit your desired mark. For bottles, you'll need to make sure you kill the beasties off so they don't turn your lagering compartment into a huge sticky mess and unless you are going for really dry, you'll need to use the kill tabs.
As far as gear goes, I think you're okay. Good luck. Let us know how the first batch turns out!
