What is the difference between a 2 seam and 4 seam "Fastball"? Aside from the fact hitters can see the rotation INFINITELY better when a ball is thrown with 2 seams? I'm not sure I understand the practicality of having 2 different pitches that are the same.

Ahhhh the grip would be the main difference. Our two seam which we refer to as cutter/splitter breaks down and away from RHH. Similar to a curve but not as dramatic a break at faster speed.
Our four seam is more of a straight hit your spot pitch.
