I think psychology and physical tells are post-graduate stuff. First master the basics.
An essential book (volumes I & II) is Harrington on Cash Games, about NLHE cash. Nice starting base. It should suffice by itself for most social / recreational home games, or soft casino tables till today.
The fact that many (if not most) poker-interested people have read it, doesn't make it "outdated". You know the alphabet or you don't.
You can then move to reading more focused and advanced stuff, or revert to Uncle Doyle's old-fashioned Super System, which I sense you can appreciate more, and make most of it, after you 've read Harrington's more systematic book. Super System (II) contains chapters about other forms of poker too, like stud.
For Omaha, the best book by far should be Jeff Hwang's "Pot-Limit Omaha Poker - the big play strategy".
It saved me tons of money by authoritatively convincing me to NOT play that game.
