If you do take the stove, the Esbit tablets (they aren't alcohol), burn about 20 minutes. You only need one, maybe two.
You only need one lighter, and matches as a backup.
Leave the 9 oz. footprint for the tent at home. Take a heavy duty garbage sack, cut down the sides making a full-length ground cover. I use one for my ground cover on backpack trips.
FYI, here are two threads to give you more ideas:
