You seem to have it correct. The only thing that's really tricky is that, on a delta with a high leg (B phase), any load that has a neutral connection, i.e., 240/120 or just 120, must be connected only to the other two phases (A or C), as you noted.

Typically, the high-leg delta system has less load on B phase than the other two, because only line-to-line or 3-phase loads are served by this phase, whereas A nd C phases serve all of the line-to-neutral loads.
