I started playing again after 27 years, so I have you beat there.
Cerveny tubas can dent easily. I'm not sure about the valves, but Rick will probably answer that.
As for oiling rotary valves, the link below is a good reference. Also, I would strongly advise that you not take your valves apart. Disassembling rotary valves is something you should leave to a qualified repair person or at least get a repair person to teach you how to do it.
