Hey Joey!
I faced a similar dust problem because I'm in the basement too...My solution was to install a suspended ceiling...It only cost a few dollars and works really well. The added bonus is that when I need to get at the electrical, I just need to lift out the panels.
I notice that you have a dryer duct going through the area. I have a bathroom fan duct going through mine, so I have put in a 'T-junction' and tapped in a small bathroom fan for my darkroom...I works really well in keeping the fumes down.

Just some ideas,
Kent
