Y'don't need any of that. Just adjust your development times a bit. In 30+ years of working in the darkroom, the best I've ever done is get the water and chemical temp "close enough." Developing paper by time/temp is a waste of time because you're going to ultimately be making adjustments not only with exposure times but in development. You may not realize that now, but the better you get in the darkroom, the more you're gonna be playing with development times, developers, and other tricks of the trade. It's the same with developing film, really.
