That's pretty freaking awesome!
FYI Orielly sells (or did a few years ago) the shelving they use in their stores. I have quite a few sets. Steel uprights, MDF shelves with steel edges front and back. Hooks for the shelves are spaced 4" apart. 12"d & 24"d x 48"w x 8'h. I recommend only where they can be anchored to a wall or a T setup. Height can be reduced, but shelves cannot due to the tabs on the ends.
As to your beam. Taylor and Sons pipe and steel in Chickasha can build you a beam/s. A bar joist setup or per-engineered floor joist may work. Watch craiglist for scraps. Last year I had a customer that had 6 leftover 14"h x 22' engineered floor joists. He gave them away.
