Ships can be purchased using CPs, or from other players. Bear in mind that the Rules page prices for ships are not the same as market prices. Production is not out yet, so you can only buy existing ships, not create new ones (except with CPs).
Weapons have not been implemented yet, and will be coming out as one of the last phases of Item implementation, which should hopefully be beginning before too long.
Your best bet for getting a ship to use is to join a Faction.
