Out of town longer than expected. Should I have anything done to the cars at this point?

I've been away from my two cars for a month now. By the time I come back it'll probably be another few weeks or month.

If I knew I would be away this long I would have inflated my tires and disconnect my battery. I just replaced both of the batteries several months ago too.

Is it worth it to pay someone I know to come by and do that for me? I'd have to ship my keys to them though.
