May I suggest two things, get a 25 sheet envelope of Ilford Multigrade IV RC Pearl to try out and buy an envelope of Dektol Developer. I really like the results with pearl finish RC paper as I really like the results of glossy fibre paper. For your situation stick with RC paper for now.

Dektol is a print developer, mixing up powder turns some people off but I really love how it keeps its properties in the tray all session long. Liquid developers seem to crap out on me.
