The first thing to do is check the fuses. If they are fine, then you probably have deeper problems. A new stereo head unit is a good idea, mostly because you can get one with iPod and USB connectivity for not too much money. As for the power top, if the electric motor is actually damaged, that shouldn't be too hard to replace. If you're really on a budget, start checking the junkyards for a replacement motor.
