I'd recommend joining a faction of some sort. It helps a lot with the paperwork and keeping track of the bounties.
The Mandalorians at least used to be a good one, haven't flown with them in ages though. There's also a few unofficial groups of varying quality, including one of my own (we're still setting up, though three of us are already operational).
Another suggestion would be to pick one or two primary employers. The GMG would be my recommendation - Sigma space is relatively tame, still some business but not the hordes of people you'll see in the Taus. And they're rather generous with their equipment when you're working for them. Bretonia's another sane place usually, though Dublin can be a bit hectic from time to time.
If you're flying solo, get a CD. No, don't argue, get a CD. The Mini or Torpedo on most fighters just does not work solo. The target will almost always run away (which is exactly why I have it on my Falcon, guy doesn't like killing). If you have a reliable wingman, though, it'll work. Or if you get a Bulldog from the Junkers.
