Dektol for a paper developer, and any brand of stop bath and rapid fixer will do equally well. Dektol is cheap and an excellent paper developer. Shop for rapid fixer and stop bath by price. They're all more or less the same. For paper, I'd recommend using either Freestyle's Arista.EDU Ultra or Adorama's house brand of RC glossy paper to start. Both are excellent papers, and not terribly expensive. You'll be making plenty of mistakes and there's no point throwing more money into the trash bin than you need to. Some guys will come on and recommend the most expensive papers because they're supposedly "better". Well, sometimes they are, but most of the time they aren't. Some folks will come on and say that you need to use fiber based paper. Nonsense. It's more expensive and a real pain in the ass compared to resin coated papers. Takes forever to wash properly, hogs up chemistry, and never really dries flat.
