I also recommend Harald Johnson: Mastering Digital Printing as a good resource.
Printing b&w - I use an Epson R1800 - can be a little tricky with ink jets, as the printer / driver try to create a true neutral grey gradient. To make things easier, and to emulate what real photo printing actually produces, the best approach is to tone your file after b&w conversion. And not necessarily the same tone all the way, split toning or equivalent mixing of curves and colorize levels makes for a far more successful print. I've downloaded some selenium, platinum etc curves that work nicely in <100% opacity.
Doing this gives a very nice inkjet print, one that can have many of the qualities of the best papers of yesteryear. But, this still isn't the quality of a really good photographic print. (Go to an exhibition of older art photos to see what was possible. Papers used to have heavy metals which gave them character tone and depth that isn't possible any longer.)
Darkroom paper is not the same as ink printing paper. While you could experiment, you'll get the best results from papers coated especially for inkjet inks. The coating technology is designed to optimize the ink droplets, so the gamut is maximized. With uncoated rag, I find I need to do a lot of trial and error to get something that's not washed out or blocked.
Printing in general - whether darkroom or inkjet - opens up a whole new area of learning and post-production! What works on screen may not be optimal on paper. You will want to apply local tweaks. But it's all so much fun!
