As far as paper goes, start with some adorama brand or some arista from freestyle. It's cheap! and it's acctually fairly decent stuff. Also, use RC for now, fiber just adds more complication to it all. Apug was the best resource for me when I was first setting up my darkroom. Soon enough you'll realize that it's acctually quite easy! You're starting off with a nice enlarger too which is nice, and if you decide to start doing medium or large format work, that enlarger will take you all the way to 4x5. I've got two of these 45mx's and really like using them, though now that I'm picking up a beseler 5x7 enlarger I probably won't be using my 45 much anymore.
