Start with any cheap, used wooden tripod you can get on ebay. Folmer, Graflex, Crown made pretty good ones in the 1920s through 1950s, get a no. 3. Use it a while and then upgrade when you know more. No, they don't have fluid head, GPS azimuth tracking or any of that. Ansel didn't need that, you don't either. The berlebach are good too, of you want to spend the money. But if you are just starting, why not try something from the classic era? A Thalhammer is a pretty good, adjustable head tripod for a small 4x5 too. Here is a good example that sold for $78 on ebay 111899992089
On developing, I'd do one sheet at a time, in a stand development process (no agitation, no shuffling). You just immerse the sheet, put a dark box over the tray, and leave for about 14 min (HC110 solution b). Come back, turn off the lights, and stop and fix. The non agitation prevents over developing the highlights.
