Chris,
 
The Glass Plate should work.  Not sure if the LEDs you are using need a driver chip if they burn out then you probably need one.  The ZXLD1362 for example holds a constant current thru a series of LEDs.  Do you have any idea what the exposure time will be can you do a quick test exposing a piece of PCB before its all built.  Just some thoughts I am sure that once you get it built you will have allot of fun with it, UV makes a big differeence.  Are you going to use it for thru hole components or SMD mostly I do all SMD,  If you do SMD you might want to check out my video series on the SMD Toaster Oven.  Reflow Toaster Oven PART
