Welcome to the board, azbigdawg. You will soon get posts from others welcoming you with all kinds of annoying gifs in them!
As for branching out as an umpire, I used to call FP, SP, and even some baseball. I found that, as time went by, I had less and less time to myself or to spend with my family, therefore I became solely a FP umpire, as that is the game that I prefer to officiate. (And it still keeps me plenty busy from Feb. through Nov.)
