It would be great getting the kit for the camber adjustment, but what wears the tires the most is, as said, toe. If your car pulls to either right or left or your tires look with uneven wear (specially on the inside, at least that's my case) get it aligned. My car has on spec camber when empty but when I seat on the drivers side the right front tire goes out of spec by a little. This seems to be a regular issue on Hondas, my old Accord, my wife's Accord and my mother's newer Accord, have the same issue they are barely on spec with someone on the driver's seat.
