why all ilford?
I recommend a range of films, not just Delta 100, try some Plus-X 125, Tmax 100, and defiantly get some Delta 400, Tmax400, Tri-X 400, or Neopan 400 as well.
I always instruct everyone to start with D76, as its the standard baseline for pretty much all developers and all comparisons. Tons of info as well.
Stop bath can be any brand, it makes no difference, just get any ol indicator stop. But be sure to check price + dilution amounts per container for best deal.
Ilford rapid fix is good stuff I like it.
Any wetting agent is fine as well, PhotoFlo is cheaper.
Dont forget to grab a HCA, hypo clearing agent. Will help you preserve your film as well as save water.
good luck and have fun.
