I would like to have my fan and the light operate off of seperate wall switches. I have power coming off an existing outlet to the 2 switches. I have seperate sheathed electrical cable (hot, neutral, ground) cables running from each switch to the ceiling box. The fan has three wires; blue black and white; plus ground. What do I need to do?

At switch connect whites together. Connect one black to each screw of switch.
At fan cannect all whites together. Connect black from fan switch to black from fan. Connect black from light switch to blue from fan. Blue is the light hot wire.
Connect all grounds at all boxes together.

I am probably too late in providing this information but you should have run three conductor with ground cable between the switches and the fan outlet box. The code requires that all conductors of any circuit run in the same raceway or cable. This is required in order to avoid elevated impedances during fault current flows that are caused when the flow of high currents is not balanced in each of the cables. This higher fault path impedance can delay the operation of the circuits over current protective device and allow the fault to last longer possibly leading to the ignition of a fire. Conductors run in separate pathways may only be run in parallel (that is connected to each other at both ends) under very specific circumstances that do not occur in homes. If you can still do so run the three conductor plus ground cable and make the connections as the previous answer outlined. You will only have to connect one white grounded circuit conductor at each end.

Hmm this one reminds me of something I need to do. I am replacing 2 flourescent fixtures with a ceiling fan/light. This is on a 3 way circuit. Question I have is, do I need to run 2 circuits to this fan, or can I share the neutral. The house is wired with NM, and has 3 conductor now since it is 3 way. But witrhout rewiring everything I an not sure how to hot the fan itself and leave the lights on the switch.

ACD:
It depends where the power source is. If it is at the light you will have no problem. If it is at one of the switches then you will need run new cable from the switch with the power to the fan.

thats what I thought, Guess it is time to get out the fish tape. I havent opened the package for the fan yet, Will there be seperate nuetrals for the fan and the light? Since all the wiring in the house is NM, I will have 2 nuetrals going to the fan now, or can I just tie them both together at the fan?
