TOP GYM RATS: Two of the most recognizable names in women’s gymnastics will participate in an exhibition at 4 p.m. today in the Anaheim Convention Center: Olympic gold medalist Nadia Comaneci and 1992 Barcelona Olympic star Shannon Miller, above. They’ll perform in what’s being billed as the Gymnastics Spectacular--$25 per ticket--which will include almost the full lineup of the 1992 U.S. men’s and women’s gymnastics teams. . . . “It’s a showcase of stars doing their best material,” one sponsor official says.
