No need to buy a book Eric. There are countless guides on the internet, though you will of course find some conflicting advice. However, Toby has done some very informative videos that will show you the basics of low n slow hot smoking. Check out
viewtopic.php?f=17&t=2898I'm pretty sure he covers internal temperatures to pull the meat off at and the other questions you ask, but I'll try and briefly cover them here so as to leave you with no doubt:
-Internal temps. People always debate these, but as a rule of thumb... Pulled pork - 200F. Beef brisket - 190 for sliced, 200 for pulled. Chicken - cooked at 165, some people take it to 185, I tend to pull it off around 170-175. Ribs - look for the meat receding from the rib ends, and the meat being tender and ready to pull from the bone. See the link I will post further down for a table.
Stall - When your meat reaches about 150-160, the temperature suddenly stops rising. This is because surface moisture is evaporating, stopping the fire from increasing the internal temperature. This can last for hours, and brings me neatly to foil.
Foiling - aka the Texas Crutch, this is simply wrapping your meat in foil to prevent moisture loss. This is often done at the beginning of the stall. It can reduce the amount of time in the stall, and ensures the meat stays moist. This can affect the texture of the "bark" on the outside, so isn't to everyone's taste. Leave the foil on for the rest of the cook.
Resting - you didn't ask about this, and may well know, but it is crucial to rest your meat. Minimum half an hour for a big joint. I leave pork shoulders an hour, wrapped in foil and a towel.
Estimating cook times. BBQ is done when it's done, through the miracles of time and woodsmoke. Whatever you estimate your cook time to be, it's worth adding to it to be on the safe side. Nothing worse than friends arriving for dinner at 7 but your meat won't be done til 10! Aforementioned table showing estimated cook times, cook temperatures and internal temperatures can be found at

Hope this helps!
PS, one thing I just thought of that a lot of people fall down on, don't rub your meat too early (hur hur). If you use a salt based rub a long time in advance (overnight for example) it will begin the curing process and draw moisture out of your meat. Opinion is divided on this, but I tend to bring my meat out of the fridge an hour before I light the fire, let it warm up towards room temp a bit, then rub it straight after I've lit my fire, so it pretty much goes straight on the smoker after rubbing.
