For whatever it is worth, here is my accumulated experience with lith printing:
I am currently using Arista Lith because it is lower priced and works as well as Fotospeed and Moersch (which have all worked well for me. I did not have good luck with Rollei Lith.)
With the Arista Lith I am using 20ml A:20ml B:1000ml water:75ml old brown. Other brands were in the same general neighborhood.
I typically leave the developer from a printing session sitting in the tray overnight to oxidize even more. It is usually strong tea/weak coffee colored by the next morning. As Max suggested, I then top off my 1 liter Old Brown bottle for the next session, and dump what is left. Sort of reminds me of that bread recipe where you save a little of the old dough as a starter for the next batch. To season the first mix, you can put a sheet of paper (any brand/type will do in your developer, and leave it there with the light on for awhile.
I strive to get the nice, pinky highlights that I like with the least amount of exposure. Since my negs are fairly consistent density-wise, I start with the same f/stop-time factor every time I print, then go up or down in time from there, depending on results of the first print. That also helps season the "new" developer, even though it has been spiked with old brown. I usually don't start getting the color I like until the 3rd or so print anyway.
I like to keep my developer at about 30c, and get snatch points of 3-5 minutes. I'm not sure if a plant warming mat or baby pig heater would keep it that warm. I found a contraption (I think called a Phototherm) that heats and recirculates water; an 8x10 tray fits into the container as a water bath, larger trays sit on top. It is thermostatically controlled and works great.
Paper: lots of people here have good luck with Ilford paper. It has not worked that great for me. I love the pinky highlight tones that Fomatone gives me, so I stick with that for lithing. I don't know why people say it is hard to start with. As long as you use tongs so as not to contaminate the paper in the developer with your fingers, and don't poke at the paper with your tongs, Foma works great.
Well, that's about it. My knowledge is exhausted. My brain is empty.
