If you're looking for information on particular kilns, there's a long "sticky" thread on WetCanvas! with a lot of posts. I haven't read it recently, so I don't know how current the information is, but it should give you an idea what's out there.
WetCanvas Kilns thread
For a good general reference on beadmaking information, you might want to buy a copy of Jim Kervin's book called, "More Than You Wanted to Know About Glass Beadmaking." It covers topics like annealing schedules as well as safety information and a whole lot of other stuff. The major glass suppliers carry it.
Annealing schedules vary according to the type of glass and the size of your piece. The annealing temperature for Effetre (Moretti) is a range between 940 and 968 F. The rule of thumb that I was taught was at least a 15 minute soak at annealing temperature for each 1/4 inch of thickness of your bead. If your kiln holds the annealing temperature correctly (doesn't go too high), there's no problem with soaking too long, so you can put beads in at the beginning of the day and keep making beads, and then let the last bead soak for as long as it needs to according to its thickness. The annealing soak isn't the end of the story, though. The glass needs to cool slowly at least to its strain point, which is 840 for Effetre. I have my kiln programmed to take 2 hours to go from 968 to 800 (I go a little below the strain point, just for safety's sake). My kiln is firebrick, so it cools fairly slowly by itself. After it hits 800, I just let it shut off and cool by itself. No opening the kiln until the beads are cool enough to hold in your hand!
