For your chainline, hold the wheel still and move the pedals forward / backward. There should not be much play. If you can move the pedals more than a tiny bit (how tiny is up to you, but not very much), you need to loosen the axle nuts and pull your wheel back and tighten the chain a little bit.
Regarding your cranks, to quote bikesdirect.com -
NOTE: PLEASE TIGHTEN YOUR LOCKRINGS, CRANKS, PEDALS ETC BEFORE AND AFTER EVERY RIDE
