Around where I mainly work, I have both an air line and and electric plug hanging down from the ceiling in those spring loaded self coilers. It saves having to deal with lines on the floor and putting them away after, even stretches out the shop entrance a ways. I like to use a metal cut-off saw outside, keep the sparks away from a mainly wood shop. Tug on the line and it disappears above, but always within easy reach. No need for separate extension cords or those air hoses that can get kinked up.
I doubt that you really need a dust system, but a good shop vac is useful.
Interesting to hear about the 'rough service' halogen bulbs, never heard of them before.
