Q1: Well we don't know for sure what the cost is, depends on the pre reqs. The cert itself will probably cost 3, but you may need to get something else first. What TimberWolf2K said was wrong on the second part, you can get Galaxies on your sanctuary continent, or if you want to get one on a different continent then your empire has to have control of the drop ship center.
Q2: Weapons are obtained at an equipment station after you respawn, or at a locker. This is important because not all respawn places have an equipment station (tower). Everything in your inventory when you die goes into a coffin which appears as soon as you choose to respawn. Exp cannot be taken away by dying. The galaxy is also free, see Q1.
Q3: Depends on the outfit.
