The rear of the bike is simple like you said. No problems there.
I'd suggest printing out the fork assembly-specific manual pages that is listed in a couple other threads. They will help tremendously. As will the multitude of smart folks here to consult if you get in over your head. And, yes, you will have to break them down completely. Go ahead and order the dust seals and other replacement parts. The powder coater will be baking the fork tubes, so they need to be devoid of all rubber bits. I cannot stress this next statement enough, so please read it carefully--make sure you tell the powder coater to not get any paint residue whatsoever inside the fork tube,
especially where the seals seat (say that fast three times!). When you get the tubes done, do not leave his/her shop until you visually inspect the inside of each tube. If there is residue on the inside, I would not leave until it is completely gone. Don't ask me how I know this...
Here's a couple of things I did when I took mine apart for coating (I did not tackle the forks myself, but the tips will still apply):
1. Have a digital camera handy. Take pics of before/during/after breaking parts down. Nothing like a real live shot of your actual work to help you remember how to put her back together.
2. Buy a box of ziplock-style sandwich bags. Tag all small parts with labels of your choosing (I used small, blank address labels), then place them in the bags. You can't put too much info on the tags--what side, what position, which hole, etc...
