As far as I know gills in beakworms didn't evolve until gilltails and such. The ancestor for this one also breaths through its skin, so I assume that's a basal thing.
Support I think is a harder question, at least from what I know. I know there's a gilltail that shows an internal skeleton made of chitin iirc, but before that I'm not exactly sure. Maybe waterworms have a very simple endoskeleton, given that they're more primitive than their living relatives?
