You install a trimpot the same way as a normal pot.

use one outer lug and the middle one to replace a single resistor.

If you are hooking up the pot to function as a resistor the last lug does nothing. You choose which outer lug you wish to use depeding on the orientation of the pot. If you use one lug the resistance will increase when turned clockwise, If you use the other the resistance will decrease when turned clockwise.

So!.. Can one simply remove the third leg from a trim pot if you are using it as a resistor?

I suppose but I dont see why you would want to, It wont take up any less space and if you decide to reuse it later.....
