I am familiar with the basic ideas of quantum field theory but I feel uncomfortable when I have to derive Feynman rules by myself for a given action (for example in non-linear sigma models or electrodynamics). Could you provide a list of good books, articles, lecture notes and/or any other sources (except Peskin), where Wick's theorem and the Feynman rules are derived from the functional integral in detail, preferably with examples?

If you'd prefer a more systematic approach using the path integral for gauge theories, I suggest you research the Faddeev-Popov method. A good source to start you off is Srednicki's textbook. – JamalS Apr 9 '14 at 18:53
See, course: Quantum Field Theory II, from 11/12 to 13/14 for a treatment of the path integral. The last lectures of the course focus on the Faddeev-Popov approach. – JamalS Apr 9 '14 at 18:57
