I tried to read some of the letters between Feyerabend and Lakatos once, I didn't get much out of it besides being pretty creeped out by how much they talked about being invovled with their grad-students (especially when you actually look at Lakatos's face). I'm not a fan of Feyerabend, and I'm not even sure he's too relevant to Lakatos's work, but the other two for sure (just knowing the basic ideas behind e.g. fallibism and paradigm shift was enough for me though, I only vaguely remember reading Popper at some point).
