When it comes to containing all the relevant info, Wikipedia qualifies. However, it is not at all organized as a learning material. There are many logic and set theory textbooks, many of them available for free (here you can find a few on logic), and I feel like they would be more appropriate than Wikipedia. One more advantage a textbook has over Wikipedia is that (usually) it contains proofs, so one can get some impression as to how working with these concepts looks like.
