And if so, or even if just a fun side venture... any input on what I should add to my ship, other than the obvious laser and refinery?
Depends on what you fly and what your goals are. Trading is broken right now, so I parked my Lakon 6, and purchased a Cobra III again. When trading gets fixed (whenever that will be), I'll go back to trading. Mining is slow to get started as you have to find a good site, but it's all profit.
Just don't do like I did today: get distracted, accidently push my throttle, crashing into a roid and losing 700k of metals and my Cobra.
