Here's a thought ( SPOILERS ):
First, consider pirates. The best example, in Star Wars, at least, is Hondo. Other than being an immensely entertaining character, he is described as a pirate, and designed to reflect this visually. But what does he do? I can think of four major events in The Clone Wars (spoilers be here): 1, he kidnapped Dooku and held him ransom, and then engaged in some unscrupulous kidnapping, 2, he attacked a village on Felucia to steal and later sell valuable medicinal plants, 3, he smuggled guns at the behest of Obi-Wan to Onderon and 4, he attacked the Jedi ship hoping to swipe some rare goods, then progressed onto slavery. There's other things, but that's what I remember distinctly. END SPOILERS
The short and long is he's a pretty consummate opportunist. He's a pirate, but the nature of his work is whatever will get him money. And he has resources; his own planet, pretty much, enough ships that he can lose several and not slow down, tanks and speeder bikes that he loses in equal measure, plenty of underlings, notoriety and booze. What more can a pirate as for, really?
I think any GM trying to build an interesting pirate organization, or any PCs attempting to operate as one, sell themselves short when they think that pirating begins and ends with Captain Hook. Unless ham and cheese is the name of the game, in which case, bring on the space square rigger. Anyway, point is: work is work; smuggling, ship-jacking, kidnapping and ransom, whatever; money is money, work is work.
Second, consider Fly Casual. Particularly, page 74, talking about the Imperial Customs Office. True, it's mostly written with Smugglers and smuggling in mind, but there is a lot of overlap between piracy and smuggling (see above). Related, y'know? Father and son. I would look into that. If you don't have it, but you plan to feature lots of spaceship shenanigans, it would be an invaluable resource.
For extra reference, find WEG's Galaxy Guide 6: Tramp Freighters and read the section on the Minos Cluster, the Minos Campaign and the characters. Pirates and smuggling, and one of the major antagonists is Imperial Customs, with their ships and MO.
