The book spec is for the bike on the side stand. You could set it to spec on the side stand, then put the bike up on the centerstand and find the resulting measurement for future use on the centerstand.
On the pre-2012 bikes the marks on the swingarm are not accurate enough for chain alignment--they're a starting point, then sight down the chain to be sure it is running straight off the sprocket. I don't know if the L2 bike has accurate marks, but I wouldn't trust them without a careful look.
Little or no need to clean the chain, but it does need lube for longest chain life. Lube every other tank of gas is a good rule of thumb, and lube every tank when running in the wet or in abrasive grit. A simple wipe with a dry cloth is OK for getting dirt off--I don't use kerosene or anything else to clean, and I don't use a goopy lube. As always, never ever run the engine while cleaning or lubing the chain--fingers have been cut off doing this.
