You might find some useful stuffs in Dilettante. Merchant Prince & Scoundrel would be my other choices. The rest wouldn't seem to relate so much...
Yeah, agreed.
Frankly, with your oodles of backgroud material, you probably already have enough when you get a core rulebook. You might find the Central Supply Catalogue, with its wider range of weapons, of interest.
Serenity/Firefly is a TL10 setting (though the vacc suits seem to be at TL12 standard) including grav control, so leave out some armours, e.g. ablat, reflet, combat armour and battle dress, but allow TL10 cloth, allow all TL10 weapons, including TL9 energy weapons, but make the latter expensive and rare. There is no jump drive in the series, but I would be inclined to remodel things slightly and introduce Traveller type jump drive, which will make your 'verse a big bigger. I suggest that you create worlds rather than using the random generation, as the firefly verse seems to have a large number of planets with terra style grav and atmospherices (the film suggest widespread terra forming). TL in many of the fringe worlds likely to be 4 or 5, and population seems low outside the core worlds, but that is all in keeping with the frontire spirit of the series ("go west, young Mal, and east and north and south and up and down, hey, just go")
Firefly always looked to me like someone's Traveller campaign diary, so I hope the background and system works well for you!
