I don't have good suggestions for a good set theory textbook. Grad school was 30 years ago, and I didn't specialize in logic.
The best set theory book that I read was https://www.amazon.com/Naive-Theory-Undergraduate-Texts-Math.... But that one is aimed at people who want to go into math but do not wish to specialize in set theory, and not at people who want to actually learn set theory.
This is stuff that's usually taught in a course called "Discrete Mathematics". As far as textbooks go for this type of material, which do you all like? I own Rosen's famous book ( https://www.amazon.com/Discrete-Mathematics-Applications-Ken... ), but it's the "James Stewart's Calculus" of Discrete Mathematics books. I purchased some really old books too, but I haven't yet found one that I like a lot (I settled for a Dover text that's mostly passable).
