Ventilation fan in bathroom

Should be simple. Not sure what to do.

I have power source coming down from attic through the wall
as 14/2 wire. I have 2 switches.
One of the switches operates a light in the bathroom. 14/2
Switch 2 operates the ventilation/heat lamp. 14/3

I assume easiest thing to do will be to run power to switch 2.
Extend power to switch 1 from 2.

I then would attach 14/3 wire from fan/heat combo to switch 1.
My breaker will not pop back on until I can make connections.
What schematic should I be using?

Tying B to B and W to W and Ground to Ground from power to bathroom
light and extending to switch 2? Moving power over to switch1 for fan in
the same manner?

Attaching 14/3 wire to switch 2 and capping off red or grounding it?
The both work separate of each other. Shouldn't this work?

I'm attaching a diagram momentarily.

You may want to stop and read the instructions that came with the unit. You say it has heat built in. Most likely this is going to require at least a 15 amp dedicated circuit, possibly a 20 amp circuit.

This is too much load to try to tie into an existing circuit.
