As far as rests go I have a Ripcord code red on my bow and a QAD on my wifes. I prefer the Ripcord, but you can not go wrong with either, I just like having the molded plastic on the prongs and not having to put felt on the QAD arms. For sights it is personal preference I believe. I switched from a 3 pin Fuse to a TruGlo Range Rover single pin. I prefer the single pin, it just clears up the sight window. I know HHA is probably a bit better, but the Range Rover is a little cheaper alternative that is not far off the HHA.
