Just starting id go with a 3pin sight or a 5pin. Depends on how you react to multi pins in your sight picture. Rests are kind of user preferance, I like fall away or limb driven where a lot peoplw like whisker biscuits or similar. Beestinger stablizers are great though spendy, theres end less options length and weights. Youll need to let us know what your plans are hunting, target or??? Quivers I preffer the octane dead lock pro.
Id say best bet is to go try some rests and see which ones you like. Same with sights, axcel and spothog have great sights, and the g5 sights seem solid.
You will see all sorts of replys but really its what is to your liking
