Paikea, I haven't had any of your profs besides Williams and Flood. You will enjoy Williams. She has very prepared lectures and a great sense of humor. Her exams are tough, but they are open book (at least it was last year). Your rule book is the most important book for the exams. Highlight the key points in the rules, the places where they "turn", and tab. She also lets in outlines, so a concise outline as well as a more thorough outline are very helpful.
I was a overly tough on Flood in my description. In fact, I seriously considered editing my post. She's very in tune with property law and will happily answer questions and go into more detail if asked. I think part of my problem was we were a dead group of students. Since she doesn't push on the Socratic method my class quickly learned that staying silent usually resulted in her going through the cases herself. Of course, that's not nearly as helpful or entertaining as having the class participate so I got bored. I don't know how to avoid the problem without being a gunner, but if you volunteer from time to time, perhaps your other classmates will jump in.
My last tip for survival at GU. The LRW class will suddenly kick into gear and you'll find yourself overwhelmed. Get into the habit of reading a little ahead in your other classes as a buffer. LRW is tough as far as being a time hog, but well worth it. Most of my classmates worked over the summer and were on par with the 2L interns from other schools.
