There are no FTL ships. There are torch ships though yes. There are also high-tech ships called 'Step Ships' that utilise a 'stellar-tap' - one end of a wormhole in a star, one as an engine exhaust, to provide limitless (or as good as) reaction mass. The technology to manufacture these engines is beyond the capability of human civilisations though, as they are acquired tech from an apparently long-dead alien civilisation.
The Machine Civilisation has developed wormhole tech, and for their own reasons one machine faction has provided several to the more advanced human civilisations.
RE: weapons - I have tried to keep weapons generic, classed together as things like 'slug pistol', 'slug rifle', 'plasma rifle', 'standard infantry rifle', 'smart rifle', 'needler' etc etc rather than have lots of makes and models.
