I'm basing this off of TIE Fighter controls, since I haven't played X-wing in FOREEEEVER. I think the apostrophe and semicolon keys divert laser power to shields and vice versa. I vaguely recall the F9 key handling laser power allotment and F8 being shields. And as for that joystick thing, you'll need to set that in the options menu; it should be ESC or at the very least before you load up the game.
AND OMG LUUUUUUUUUUUUUUUUUUUUUUUUU <3 <3 <3
