Try this for static sag, bike on stand, measure from axle bolt to fender or something straight up from there. Bike off stand, should sag about an inch. (all bikes are slightly different). Race sag= sit on the bike where you would normally ride, have someone hold the front off the bike, get a third person to measure again. Should be around 4" or 1/3 of total travel of rear suspension. Again these are ballpark figures. If you can't get close to these numbers the springs or wrong for your weight. Adjustment is made by the 2 locking rings on the rear spring.
As for as the clickers think of them as the release valve on a hydlralic jack, turning them in or clockwise slows down the oil flow to that circuit, but they do have a bypass circuit so you can't just stop the flow by turning them in all the way. I would start by closing them all the way, count the clicks till full open, whatever it is say 18, then start at 9. There is no 1 set up that works for everything, hard pack is different then sand, supercross to woods, etc. So its whatever you like, just my way of thinking of this stuff.
