Like most people here I found it all surprisingly easy.
1) Is there a good website or book where I can get a primer on color printing?
This website, photo.net.. but really all the instruction you need comes with the chemicals. Here and photo.net will just give you some insights to experiences but everyone's set up and more importantly method varies so don't take it as gospel. I recommend a book, The Darkroom handbook.. useful but equipment wise somewhat dated.
2) Is it way more expensive/complicated than printing b&w and are the supplies readily available?
I rarely pay attention to the cost, about the same maybe.. as for complicated.. identifying colour casts and removing them without bringing in another can be a challenge (but fun too) however once you've done this for one neg, all other photos on that neg type will be within a small variation of those original settings.. so easier than B&W in someways. In the UK I know of at least 3 places that will supply me with everything for my colour darkroom within three days to my door. I imagine there are even more in the US.. ignore those strange types who can't seem to find anything.. maybe they don't like buying online.. in which case you could be screwed.
3) What are the basic chemicals do I need to get started?
I'd try a room temperature kit, I use Tetenal, I've tried a 35 degree kit but didn't notice a difference, in fact the saturation in the room temp kit was better I found. It'll be a lot easier and less frustrating whilst starting for the first time. If you become convinced you want 35 degree kits, fine, but do that later, don't kill off your enthusiasm waiting for the temperature to come up and trying to keep it there.
Other than that you need a roller drum or trays or a nova slot or a machine of some kind. I recommend Nova slot processors, get one with three slots, the chemicals keep for ages unlike trays, the consistency is great, and there is no cleaning or drying like a drum.. machines maybe better, but only because they're automated.
Soon as you get the first print out all your concerns will melt and you'll realise you just need to twiddle a few knobs to get a massively satisfying experience and amazing prints.
