I have the Property E&E sitting on my desk, and it's okay. It's not the equivalent of Glannon's CivPro or Chirelstein's Ks, but it's something.
I found it most useful for RAP, future interests, and some common ownership stuff (tenancy by the entirety/tenancy in common/joint tenancy), though I warn you that your professor will generally prefer good citations of cases and their discussion over BLL pwnage.
I don't know anything about legislation or ConLaw. But the 5th amendment and Takings clause are crucial for a Property unit.
ETA: if you want to get ahead for next semester, I would ask your professor for the syllabus. There's no need to learn the nuances of bailments before finding out that your professor never covered it (except for a minor gloss during McAvoy v. Medina), as I almost learned the hard way. I didn't read it in advance, but I could have seen myself doing so.
