Salamander Flats for camping up in American Fork. Obviously there is a fee for recreating in AF canyon, but the camping is free at Salamander Flats. No need for 4-wheel drive either, if that's a concern. I car camp up there with my prius occasionally. There's a pit toilet, a few fire pits if I recall correctly. Good views.
IME is an excellent shop a little north of AF.
I can't give you too much info about the Maple area. Good luck.
Go to mountainworks in Provo. (It’s closer to af than ime too.) The owner has put up a ton of sport routes in AF and maple and all along the wasatch front. Names Darren. Wrote the guidebook for maple. Cool guy.
Far from an expert but maple canyon has really beautiful camping. One of the designated camping areas has a couple very good sport climbs right behind it. One of the climb is below. There’s bathrooms but no showers or water if memory serves me right. However the town is only 10 minutes away.
