Base model shocks are pretty simple. Loosen the compression adjusters all the way counter clockwise and add compression where needed. You want the suspension to bottom out every now and again to make sure you're using all the travel. Compression speeds are based off the speed of the shaft, not the speed of the vehicle. Slow speed compression is stuff like smooth jumps and g outs. High speed compression is going to be choppy stuff like whoops, flat landing jumps, roots, rocks and "squared" edged objects.
Ride height or spring preload is up to you and your terrain or need for ground clearance. Hope this helps.
