Yeah, the missiles were pretty superior so far. Maybe throwing in some decent anti-missile weapons early in the game. Look at Deathwalkers D2-Gold mod. Some very usefull anti-missile weapons have been used in it.
About the gravitic weapons. My thought (maybe far too uncreative and simple) was to implement every weapons class (AM, EM, Gravitic, Ionic, Laser, Matter, Molecular, Particle and plasma) and just make them like ordinary weapons and just some of them will have special abilities. Like the mass driver, it can destroy a moon (when of sufficient level). Basically the weapons are just the same but with another name. But I created the weapon creation sheet with minor differences between the weapon classes. This gives a tiny bit of difference between the races and weapons.
I'll mail you an similar scheme like you've made of the distribution of the weapons. I can't say when I can mail it, but I'll do my best to do it before the end of this week. With a little bit of luck I have a very special friend comming over...
