Looks like you got a recast. Nice piece, but not from the original maker.
Anyway, your question revolves around paints and equipment. Not familiar w/ your compressor, but the airbrush is one of the better ones for sure. As for paints, I would recommend Freestyle, Golden, ComArt or FW inks. They are all airbrush ready and do not need to be thinned to spray. If you've never used an airbrush before they will take a little getting used to, but they are the best out there right now.
You're also going to need LOTS of putty to properly assemble this piece. Recommend you get some Aves expoxy putty from here:

Let me ask this....is this your first kit?
