Nice decals. Good luck with your build. I’m also a happy rider with this frame!
For an 160mm disc rear you need a flat mount to post mount adapter.
On the front for a 180mm disc you problay also need an adapter.
I’m using two 4 piston brakes. Bought them at:

For the rear shock I bought these products: purchase two of these packages and use the widest bushings for the front.
RockShox Rear Shock Mounting Hardware 3-Piece 1/2" for Imperial &
Metric Shocks - 8mm - 8 x 30,0 mm. (2pcs)
The are delivered with assummetric size bushings.
For the rear side, you can use:
RockShox Rear Shock Mounting Hardware 3-Piece 1/2" for Imperial &
Metric Shocks - 8mm - 8 x 16.0 mm (1pc)
I use it with: ROCKSHOX SIDLUXE ULTIMATE 3P SOLO AIR REMOTE SHOCK 210x50.

First real snag. It’s been more than 10 years since I have completed a build. There are now more "standards" in bike parts to match up.
I bought a set of XT 8100 2 piston brakes in advance of the frame arrival. It looks like I have the wrong setup for this frame. A few questions.
1. I think I have a post mount caliper. Can someone confirm?
2. I think I need a flat mount caliper. Seems like these are road/gravel type.
3. Looks like I need an XT 8110 caliper to mount to the frame
4. Do I also need an adapter for 180mm rotors? Or downgrade to 160mm?
Thanks in advance.
