Welcome, Larry. Sounds like you have a nice stable of well-regarded RF cameras, so now it all turns on what you want to do with them.
When you say you want to process your own film, I will presume you mean B&W. It is possible to do your own C41 (color print) and C6 (slide film), but not many do - it tends towards the expensive, and the chemicals are a bit more dangerous, temperatures and times a bit more critical.
You don't need a darkroom to get started doing what you describe (process, scan, print). All you need is a dark closet or a changing bag to load the exposed film from the cartridge to the light-proof film cannister where the chemicals will go.
There are so many choices with regard to film, chemistry, and even equipment, that it is difficult to give advice that is meaningful. Everyone has their own 'pet' choices and they all work well for those who tend to advocate them.
In generic terms, you need a changing bag (optional if you have a dark closet), a developing tank (plastic or stainless steel), with film reels inside (plastic or stainless steel). You'll need a good thermometer, a timer, access to a sink with running water (need not be dedicated), and a place to hang your film to dry that is relatively dry and dust-free as possible. You may also choose a squeegee to get the water off your film before you hang it to dry (optional).
For chemistry, you need a developer and a fixer. Nothing else is absolutely required, but some people prefer to use them - such as stop bath, hypo clear, and photo-flo.
For film, you have a choice of Kodak, Fuji, Ilford (the biggies) and a variety of other brands made by Eastern European and Chineses companies like Efke (Adox), Foma, Forte, Lucky, and so on. All made in a variety of speeds and with different primary characteristics, and everyone again has their own preferences.
If I had to throw out brand names and types, I would say (and this is strictly personal preference):
1) Film - Kodak Tri-X or Ilford HP5+ Both versatile, both used by many, both very well understood. If you have problems with these, there are many who have used them who can give you advice. They also can be used a higher and lower than rated speeds if need be.
2) Developer - Kodak D-76. I understand Ilford ID-11 is the same stuff. In any case, the gold standard of developers - if you follow the directions even vaguely, you will get printable / scannable negs.
3) Fixer - Doesn't matter. I like Kodak Rapid-Fix, with hardener, but I don't think there is much difference in fixer.
4) Developing tanks - Kindermann makes nice plastic tanks, Nikor makes nice stainless steel. I prefer a third path - 1950's Kodacraft 'ravioli' aprons. But I seem to be the only one...so whatever you choose will probably work well. People seem to polarize along what works for them in this regard.
Other than that, all I can do is point you at a resource for purchases that I find useful - Freestyle Photo in California:
Best of Luck and Welcome!
