another suggestion would be to get Steve Anchell book (s) Darkroom cookbook, Film cookbook. Interesting reference matarial as it will give you options with projected results. I.E. this film with this developer will increase grain, enhance sharpness, etc.

I would also second or is it third the suggestion to pick of set of tools and really work with them until you have a good feel and are working with consistency.

As to the selenium. (after suggesting one paper!!!) Bergger neutral does not like to shift to eggplant nor does Luminous Neutral. At least that is my experience in my environment. Both papers are nice as well. I was surprised when I tested them, as I usually use graded Seagull Oriental for 95% of my work.
