First things first, 3 pullups ain't bad. Remember that most of the western world is sitting in chairs all day long, going home and doing a few weary out of breath thrusts into someone else's junk and then plopping over unconscious to start over again tomorrow.
Most of the western world is heading in the direction of the sedentary cross-section and not the triathlete cross-section:
Anyhow, yes, you can progress with bodyweight exercises alone to the point where you're totally jacked. It just requires much more complex programming and generally a lot more time than with barbell movements, which is what you're seeing now since your progression is stalling. How do you get enough volume of work in when you're stuck at 3 pullups? That can be tricky. I'm not going to be a pain in the ass and tell you "NO YOU BARBELL NOW" since you're going to do what you want to do.
Look into Convict Conditioning, that's a popular bodyweight movement progression system.
Damn. Excellent motivation for leg exercises.
