And I use THIS light:

Thats my setup...where should I put my fan? Which port should I use? What should I do with the extra ventilation ports? How do I avoid light leaks through the fan and bottom intake ports? I know I should get an air cooled hood but its out of my budget right now. I have to work with what I have.

I would suggest an air cooled inclosed light those three items you posted would also make a great convection oven .
