To do a FTL jump in the viper is pretty much the same as any ship, just open you Sector Navigation map (Press 'N') and select a system inside the transparent circle.
Currently Bigpoint have no plans for the Galactica to be used other than the main hub for you character. If you mean the Dry-Dock in Delta Canopis then that is a Carrier Dry-Dock and they have already been released as ships to be used.
Also your spelling is awful, please use spell check next time (luckily I could understand what you were trying to tell me). Oh don't forget Capital Letters as well...
