a) Don't know, don't use them.
b) First, weapons fire from left to right so when designing ships you want to place shield busters before the regular weapons. Secondly, in tactical combat you can choose which weapon to fire after you have selected the ship in the screen to upper right with the ships weapons in. Just deselect the weapons you don't want to fire. To select the rest again it's easier to select the ship again then clicking all the weapons. Fool around with it a little and you'll figure it out.
c)Facilities and units don't have maintainance, only ships and bases. Yes, mines, satelittes, troops, fighters and any other units cost nothing to maintain. Nor facilities. Great, huh?
d)Don't know.
e)Not that I know of. Compared to SE3 the ingame help sucks. It's no help, just a list of components. And just the ones you have tech for in that particular game to boot. Not good imo.
I agree about the interface, it has some serious shortcomings. But the game is so good I can live with that.
