The Arista EDU.Ultra film is FomaPan. Pretty good stuff but I've found that for me, its effective EI is at least 2/3 stop slow. This may have more to do with my processing technique and chemistry than the film itself. YMMV.
At one point, the Arista EDU (no .Ultra) were Ilford but that was some time back. I think they are now Forte (defunct now) and possibly some Agfa. Forte and Agfa B&W are no longer made so what you get today as Arista EDU may not be the same as what you get in a year or two.
That said, if this is your first foray into developing, you might be better off with FP4+, HP5+ (Ilford) or Tri-X (Kodak) as your first batch. A brick of those (or a 100ft roll and spool your own) is a good investment. TMAX100 and TMAX400 are also good films too as are the Ilford Deltas but I personally like the "old school" look so I just don't use them much.
Hard to go wrong, starting out with D76. Or you can start out with Rodinal and learn a lot too.
The house branded developers from Freestyle are good value too. Arista-76 for example is formulated to match D76, and cheaper than a bag of D76. But I don't think they come in smaller than gallon size. The liquid concentrates are nice but I only tried a single bottle, years ago, before reverting to Rodinal for most of my roll film.
By the way, I just use plain water for film stop and a mix of 1+3 5% vinegar for paper stop now. Cheaper and works just fine for me.
Pick one film, one developer, one fixer, one HCA and have fun! Stick with it for a while until you get predictable results then start investigating the creative control you get from different film / EI / developer combinations.
