Yes, hook up the particle filter before the shop vac. It isn't going to collect much dust, but will allow the larger particles of media to fall out before getting to the filter. I use a HEPA bag inside my shop vac, as most generic paper filters will still allow the fine dust to get blown out the vac too.

The PVC will work, as long as it is heavy enough to not collapse under vacuum.

Install an LED bulb for the light and it will help. I modified my cabinet for 2 small flood lights in the upper, front corners to see what I was doing.
