Are we allowed to carry weapons, and if so, what sort of weapons are we allowed?

I could understand if you don't want us carrying energy weapons, since an accidental misfire could puncture the hull. Or explosives. 

Do weapons have to be secured in a weapons locker?

You are allowed to carry weapons and weapons being carried are almost primarily your choice and the choice of your character. 

Energy weapons are probably the most common weapon in the universe. 

They do not have to be secured in weapon lockers. Though, remember, "actions = consequences"
