Re. working experience, why not the Armed Forces?
I am just guessing, since I am typing from Europe, but you make some experiences that cannot be made anywhere else, keep fit, get a training, somemoney, too and if I remember correctly there are some advantages in joining a postgraduate course afterwards.
I was a part time army officer during my undergraduate course, it took a couple of year more to get my degree but it was well worth....
