The tool needed is a 8mm hex (not 12mm like book said).
Drop air in both legs and open Right leg (no need to remove oil). Can be done with a 7" hex if you completely drop the fork (keep removing air from Left leg and completely bottomed out by pushing down). I found that the stock setting was 3.5 turns from fully counter clockwise-CC (at least I doubt the guy who I bought the bike from ever adjusted it because it felt like it had no damping). I finally started noticing a difference about 1.5 CC out then left it at 1 turn from fully CC I believe.
To tell if you have any damping you should be able to hear the oil suctioning through the valve. If you don't then adjust CC till you do and can feel it (don't go too much or else it may not pop back up in time for the next bump). Only riding will tell if you have too much or too little.
A regular tire pump and air guage are adequate for setting fork pressure, you don't really need the little expensive pump. Just start off easy to not blow out the seals (I used a foot pump but pressed it with my hands and could only get the fork to 35 lbs).
