Hello..
It looks like your motor has brushes, and if so....
Just a few "general' comments.

" After cleaning it "
Did you take it apart to clean it? Check the condition of both the brushes and the commutator? Clean out the carbon dust (from the brushes)?
Did you reinstall the brushes in the same locations and orientation?
If you didn't you may want to do so. Don't forget to inspect the bearings, (others, please chime in!).

"I also need to figure out which way to rotate the motor properly. I think it needs to turn clockwise."
Most all DC motors can run either CW or CCW. The only concern here would be that if while it was being used did it run CW CCW or both. If it was used in both directions it shouldn't matter which direction you run it. The issue at hand is how the brushes seated to the commutator. With new brushes and a clean commutator direction shouldn't matter.
Also, there is a "common" opinion among motor manufactures that a DC motor (with brushes) should be mounted so that the brushes are "horizontal" and not vertical.
The reason being that the carbon dust will settle to the bottom and you don't want this conductive dust shorting from a brush to the case.
I'm not sure this is really an issue with the motor used as a wind gen, most manufactures are assuming that the motor will be mounted to a common frame and being driven by some sort of DC drive, and this mounting practice is more about personal safety and protection for the DC drive.

"Tower:
I was thinking about 2" diameter piece of steel conduit. Not sure how tall yet."
As already mentioned, this may be a bad idea. Conduit is pretty soft stuff (it's made to bend).
When much younger and not so bright I used conduit for antenna mast. I learned real quick how to make pretzels!
That looks like a beast of a motor, and it's going to need some serious support.
Have fun!
