I use the Ilford chemicals -Ilfosol 3 for developing and Rapid Fix for fix, and I just use water for my stop - 2 - 45 sec baths. As for times, if you peel the label on the chemical bottle, there's a list of time and temps to go by. Plus a really useful website is digitaltruth.com and go to the massive dev chart. It has all different film stocks with different developers and gives the developing times. Quite useful.
