My visual analysis is this:
Crew:
2, Pilot and Weapons. This is due to the cockpit glass design more than anything. There are 2 forward facing panes with the associated side panels and top. Vanduul fly their ships in a prone position so this would give both room. The top one would likely be the pilot while the bottom would be weapons.
Weapons:
1 Gimbal Cannon(S5 Neutron probably)
24 Small Torpedoes(S4/5 perhaps)
2 Automated/remote turrets. 4 small weapons each. Anti-Missile or anti-light fighter weaponry.(S1 probably)
4 Neutron weapons(2 below main cockpit glass by nose, 2 beside the upper glass)(S2 or 3)
(Probably a couple more weapons in the Wings too)
Engines:
3 S3/4 Main, 2 S2/3 auxiliary
Thusters - Unknown
Nose:
Unknown, possibly sensors, some defense system or shield projectors.
