google this site.. more info on lith printing than you will ever require.
I think Bob means "Search the APUG archives".
The thing is that I have been search but still had some questions like for example "multigrade or fix contrast paper" to be used.
I use one of those flat glass thermometers in the developing tray to keep track of the temperature.
Oh, and buy a tray warmer - just find an old buffet warmer with a heat control, something like this. Get the biggest one you can find, and be careful - on High, they are stupid-hot - I think that's why they're no longer made, you can really get a burn when it's turned up.

Are you heating up the developer to speed up the snatch time?
Yes indeed - with straight (or first pass?) lith printing, development times can be 30 minutes or more. Going up to 30-40C doesn't seem to affect anything but developing speed (I believe Tim Rudman states this in his first book). I've done prints that took close to 50 minutes. Not a lot of fun when you're dialing in exposure and burning!
You can speed up times with stronger developer, but since it's lithographic developer, it gets contrasty/gritty/etc pretty quickly. Lith really works by being very diluted (2nd pass mixes are often 5-5-2000 - that's pretty thin!) The more dilute, the more color, or so they say.
