It´s been a long time since I last used Aerotech units, so my skill sthere are rusty at best. Checking TW p. 245 and such, I can´t find anything about the weapon distinctions. I wouldn´t mind if you´d point me to the right section.
As for the rest, it´s in a mercenary TRO and availlable as loot from conquered worlds, something the cappies are not inexperienced in :P
You'll want to start on p. 242 and read through from there. That should among other things yield that
(a) fighters are only allowed to use their nose- and front wing-mounted weapons in air-to-ground attacks (p. 243, "Firing Arcs");
(b) a unit may "fire one, some or all of its direct-fire energy and pulse weapons when strafing" (also p. 243, "Strafing", second paragraph); and
(c) a unit may "fire one, some or all of its weapons at the target, except for bombs" when striking (p. 245, "Striking", second paragraph). Bombs are exempt because bombing is once again its own attack mode (two of them, actually, dive and altitude bombing respectively).
The whole section has also received a bit of errata, which you may also want to check out, but none of it changes these three points.
