Rest.. I would personally get a N.A.P. QuickTune 3000 Micro, I tried the Trophy Taker Shakey Hunter and wasn't pleased with it.
Stabilizer.... Stealth... the best there is..... nuff said.
Custom String... Winners Choice

I just ordered a Winners Choice string and cable for my BowTech, and the total was $76.50 which includes shipping and handling. I got mine from
www.thebowrack.com I hear alot of guys talk about spending $100-$120 for a WC string and cable, but heck, you can get them at the the bow rack for $70 plus shipping and handling.
