To the below I'll add - as a educated guess the last one or two letters (FM, BS, G, B ) is the code for finish options - FM = Flame Maple top, B = Black, G=Colour, BS = Sunburst
Golly, there are a lot of options in the range - never knew the were so serious about the artcore range.

No, they're mostly hollowbodied/semi-hollowbodied, thus the "art" part, as the full hollowsbodies have a sculpted face.
Basically, if it has a T in the model name, it has a tremolo/vibrato bar. If not, like an AF75, mine, it's just a nice guitar with a standard tailpiece.
The names, I don't think, have a big difference in what you find or have, but this is what I know:
S=Semi-Hollow (I Think)
DG=Dream Guitar (it looks like a White Falcon, which was made to be a "dream guitar")
As for the numbers, they denote the body shape. The 75 is a big, single cutaway that it's mostly for jazz, etc., as you can't easily get to the highest frets.
