as far as the fan, you've got two options
1) use a 120volt ac
fan, and wire it into the switch for your lights. I'd need to know what your fixture looks like to tell ya more about this
2) use a 12 volt dc
fan and a power pack, and put it on the timer with your lights.
radio shack should be able to hook you up with the fan and the power pack, and go to a hardware store and get something called a "cube tap"... it's a molded plastic jobbie that turns 1 outlet into 3, handy for using with timers.
