Welcome back to archery!

Sights? Hard to go wrong with any of todays quality brands. Expect to pay $50+ for a decent sight set up. I myself use a Vital bow gear proslide.

Quiver- can't go wrong with a Quicky or Bohning Lynx
Myself - Bohning Lynx-6 arrow model.

You might want to go to a pro shop and do some window shopping and see what they have to offer.

Good Luck with it!
