I'm new to developing and probably too dumb to even ask the right questions, but I have been looking at the various chemisty listings online. I "think" I understand that c-41 is for color processing (and some b&w), e-6 is for slide developing (b&w? color?) But I have seen other references to K process etc. What are the different processes? But several questions: what is for b&w only? Do I use the same developer for prints as for film? Do I need to use a commercial stop or is water sufficient. What about fixers? Additives for final rinse? Is there somewhere to find this information all in one place on the web? I have some books on darkroom techniques, but the explanations are unclear/confusing/non-existent.

go to ilford's website and check their tech pdf. they go into very good detail about all the equipment and chemicals that you will need. The chemicals do not have to be ilfords .
for black and white film you will need a developer, stop bath, fixer and some photo flo
for printing, a developer , different than the film type, stop bath, same as for film but a stronger amount and fixer, same as for film but usually in a different ratio.
if you use a T-4 fixer you can use water instead of a stop bath for both prints and film. this fixer is available at the Photoformulary.
depending on the top of film developer , stop bath will be better, but some folks use water.
Stop bath is not expensive and you use very little so i would recommend it for the film as well as the paper, unless you are using a PMK developer ; which is not likely.
If you are using RC papers there is no need to use perma wash before washing your prints, and if you use ilfords archival washing procedures you will not need it there either.
You are correct with your observations about c-41 and e-6 chemicals being color tools.
Welcome to a great new adverture. have fun.

Thanks Ann. I'm checking out the pdf and it looks like just what I needed. It's great to have a helpful group who will respond to others and help dumb newbies. I hope that someday I'll be able to help someone else. Thanks again.

E-6 is the process for developing most color slides. True black and white slides are developed with black and white negative chemistry in a more elaborate process, or such is my understanding.
The K processes are for Kodak Kodachrome only and are proprietary, meaning if you buy kodachrome and shoot it, the film has to go to Kodak for processing. I think it is K-14 now. You can buy pre-paid mailers for K-14 from www.bhphoto.com and they are cheaper than drug store photofinishing, but it takes longer.
I don't know that there is a code for the true b/w negative process, but all the right chemistry says 'developer for black and white negatives' or some such explanitory. Also, the chemistry should be categorized according to use on a good retail website like B&H's or Calumet's (www.calumetphoto.com).
