Good choice on the car Justin
Run the belt with enough tension that you can still twist it by 90degrees or so. They seem fairly happy across a range of tensions in reality.
The wishbones should move while the pins generally don't rotate. If yours is binding then maybe clean up the side faces of the plastic wishbone. Sometimes you can get a small step on the mould split line that cleans up with a needle file.
You can play with droop a few ways - most ppl leave it alone, but if you want then you can wind the ball joints more/less onto the shaft. You can also add spacers under the piston but that means that the shocks need to be rebuilt each time you change the droop.
The best way I've found is to use carbon spacers under the rear shock tower mounts. You need to get the latest aluminium upper housing for that but they are a worthwhile upgrade as they also allow you to fit shocks on the rear.
