I agree with you on both of your points. Regular Hollows and Menos Class Hollows should've been explored more before the Arrancar were brought out. Concepts like hybrids just seems like something to introduce long into a story. And as much as I think a second Resurrección for Arrancar would be interesting and may be a possibility, I am also under the assumption that most Arrancar are at their full power with a single Resurrección (Ulquiorra being the obvious exception) making a second form unnecessary.
