Let me add something here that will get you back to where you started if something goes terribly wrong (very unlikely- it really IS simple): Write everything down and only make one change at a time. Measure the front end sag without making any adjustments. Count the number of turns in (clockwise) of your preload adjusters. Turn the front adjusters gently- you'll feel it when they reach the end. Then turn the adjuster back where you started from. Do the same with the shock- measure sag, set the adjuster to 0, then back to your starting point.
At this point you are ready to make adjustments. I concur with setting both the front and rear sag to 40mm as Greywolf suggested, at least as a starting point. Record your adjustments. Ride the bike for a bit and get used to how it feels. Make sure your tire pressures are set and recorded also- they are a critical component of suspension adjustment.
I'd play with tire pressure after setting the sag. Currently I have a Trailwing on the front and a Tourance EXP on the rear. For all street riding, I run 39psi in the front and 36psi in the back. The front has over 11K miles on it and looks like it has at least 5K more left in it. The rear has about 9K on it and has several K more miles on it if it doesn't get too much more square from the commuter miles. Rear has chicken stripes of about 3/4" or less on it.
Experiment and have fun!
