Tropicals & Tender Perennials: ID help please?, 1 by grampapa

This was my mother's hoya and I brought it home when she passed away. I recently decided it was getting too much sun (southern window). It rewarded me for moving it by blooming almost immediately. I've looked thru the pics at Aloha Hoya and still can't ID it...I just get confused :-). I would also appreciate some basic care tips. What would be a good location for it? And it probably hasn't been repotted in forever(?). I know they bloom better if they're somewhat rootbound, but should I at least give it some fresh soil, pot it one size up, just leave it alone?
