Congrats on getting the car.

First thing to do is change the battery on the dead key. The other one I would take it to pieces and see if there is anything up with the trunk buttons internally. Did you get a warranty? I would take it back and get them to sort it at the first instance.

Adding cruise control & OBC is easy on our cars. You need a couple of plugs, some VW wires and a 4 stalk indicator unit and a quick trip to a dealer to enable in the computer. Maybe a project for the future, took me less than 2 hours to do mine.
