The light is positioned about 16" above the screen. Use a piece of foam cushion cut to the inside dimensions of your screen.

Place the cushion on the table, lay a black cloth over it (a tshirt works fine). Place the screen over the cushion, which will be inside the screen, then position your transparency. Use a piece of heavy glass to hold the transparency down. My glass is 1/4" thick and works fine. Make sure you tell the glass shop that the glass cannot block UV light! Have them cut it to just over the size of your screens. Also have them sand the edges so you don't cut your hands.

Expose the screen and wash it out. You'll need to dial in your exposure times using an exposure calculator:

I see 156 as the golden number for a lot of things, but most of my screens are 110, and i print everything through them. It will definitely leave more ink on the garment, but that could be a good thing. 156 is a nice middle ground for most ink types. I don't print plastisol, so I cannot speak about that, but anything water based works fine.
Check out this thread. I recently redid my exposure unit with this light. It's less than 30 bucks, and while I and the OP had a box to put it in, you can definitely rig something up to project overhead. It has a bracket on the light for mounting so this shouldn't be an issue. Here is a link for the light.
Depends on your emulsion and height, but I used Ryonet WBP [available in pints!] with a light height of 8.5 inches for 4 minutes. This emulsion is forgiving and you can fall in a range and should still be okay.

You could of course skip all this hassle and headache and get a preburned screen.
