Working form my limited knowledge:
1) If you mean anti-fighter/bomber by "anti-ship", no. There are different capital ship weapons that they use against fighters. The EA have Gattlers and Blasters (alongside flak which most factions use as standard), the Terrans have cluster shotgun weapons (among other things) and the Vasudans use spatial charges which are like energy flak or something. Bombers also have non-standard special armaments, the Terrans have PAC systems which are sort of like heavy plasma cannons for when they're out of bombs, the EA (I think) have some sort of bomber-based railgun system, the Vasudans have local SSM torpedoes (done differently to WiH) and the Shivans have bomberbeams. In INFASA the EA will also have, like, nanovirus ECM attacks too. This is just the publicly revealed stuff, there's almost certainly more sekret stuff in the works.
2) Unless things have changed, they will be closer to INFA.
3) I think they have kinetic weapons that keep enemy ships at a distance or something. They also have bloody huge blob turrets. Plus lots of other stuff we don't know about yet.
