I have a power wire from a junction box in the attic to the ceiling box for the fan. It has black, white and ground in it. How many wires do i need to run to the switch box, and then how do the wires hook up to get the fan on a separate switch than the light.

i would go with a three conductor to save wear and tear on the fan pull chain switch,since you're starting from scratch.

Like LarryG said, use a 3 conductor (+ ground) for this. Even if you are using a pull chain instead of a wall switch for now, installing 3 wires will make it easy to change that sometime in the future.

If you are installing 2 separate wall switches, connect it like this:

In the ceiling box, connect the incoming white wire to the white wires for the fan & the light. Connect all the grounds together. From the 3-conductor cable, take the white wire, put some black tape on it to mark it as a power wire, and connect it to the black wire of the incoming power cable. Connect the black wire of the 3-conductor cable to the black wire of the light. Connect the red wire of the 3-conductor cable to the wire to the fan (black, or possibly blue).

Then in the wall box, take the white wire and mark it with black tape at this end, too. Then connect it to one side of BOTH the switches (may need a short pigtail of wire to do this. Then connect the black wire to the other side of the light switch, and the red wire to the other side of the switch for the fan.
