I'd go for a cobra or a toad alarm.
Have you considered that window film stuff for the windows ?? (the stuff like sticky back plastic, which holds the glass together when it's smashed)
It'll be a cobra alarm, there should be some paperwork for it too (in with all the manuals etc)
As for worrying about the wheels, a couple of locking nut per wheel ought to slow a theif down a bit, should someone come to steal them.
