I have a small studio room (about 2,5m x 3,5m) in a rented apartment. I've recently treated it with the Auralex Project 2 set and the Auralex MoPad XL for my monitors. I am very impressed with how it changed/improved the sound; it's just day and night.
The main challenge was to stick them to the wall in a non-destructive way since I will likely move at some point in the future and I don't want a damaged wall or damaged panels. I've found a solution in the 3M Command strips: the medium sized strips for the 60x60cm wall panels and the large sized strips for the bass traps.
My main concern was if they would stick to the foam material the panels are made of. The answer is: yes, they definitely do. And yes, they also come off without damaging foam or wall. But no, they are not reusable: once removed from the wall they will loose their stickiness.
Total number of strips needed:
You need 2 pairs (= 4 strips) per panel or bass trap to hang them from the two top corners. You could use 4 pairs ( = 8 strips) to stick all 4 corners but that's overkill really.
24 panels x 4 per panel = 96 medium sized strips (or 48 pairs)
8 bass traps x 4 per trap = 32 large sized strips (or 16 pairs)
That's 128 strips or 64 pairs or 16 packages (4 pairs per package), costing around 100$. Do check the number of pairs in a package since there's different sizes. And remember that you need 1 pair or 2 strips to attach one corner of a panel.

Thought this might be useful if you were thinking on doing the same
