If I'm right, and I'm probably not, it's an either/or case. You either have the SINCGARS, or the VRC-110 in the M-ATV. When looking for pictures and information to draw up the VRC-111, I didn't really find much on it being used. Mostly the 110 and most often the SINCGARS. I think it would be the VRC-84, right? I think for intercoms, the VIC-5 would be the right set with the VRC-110.
With regards to material names, I think you might have ordered the parts in the "right" material. Shapeways just changed their whole naming convention. The "Smooth" plastic is the same as the Frosted Detail plastics I think. Smoothest is probably the same as Frosted Extreme Detail.
Also, for M-ATVs, I think there's still only 2 1/35 kits out there: 1 by Kinetic and 1 by Panda. From what I've read, both are accurate shapewise but Kinetic is overscale by a noticable amount when placed side-by-side with the Panda kit. The Panda kit isn't too bad to assemble but nonetheless, it's a Panda kit and pretty hard to assemble (from on going experience with that one). Panda includes no interior whatsoever except the bare bones to call it that. Kinetic provides some interior stuffs. I'm sure there are more significant differences but I can't remember them.
