Dear Keith,
The McCall book is excellent and really fits very well with the course as I present it. You should find it complementary in almost every respect. If you can get it inexpensively online, you should snap it up.
Of the remainder of the books on the list, Veatch’s Two Logics would introduce you to questions in the philosophy of logic, and especially the philosophical/epistemological/metaphysical differences between traditional/Aristotelian Logic (which is what is in the course you’re following) and modern, mathematical logic.
Best wishes,
Gerard Casey
