I agree with everybody else -- don't sink a lot of money into gear until you finish your class. From time to time, people run into obstacles they can't clear when trying to get certified. Their ears won't cooperate, or they have great difficulty learning airway control, or they discover that they don't like diving as much as they thought they would.
Once you are certified, it is good advice to rent a few different kinds of gear to try, if you have the ability to do that. But most of all, you will dive more if you own gear. I bought all my stuff as soon as I finished my class, and within six months, I had replaced a good deal of it (especially the fins and the BC), but I still don't really regret having bought gear, because it got me diving, and diving brought me the people who helped me realize I had the wrong gear
The biggest thing, I think, for beginners, is to get a BC that really keeps the tank stable in the middle of your back. Experienced divers have learned to balance that big keel, and as Diver0001 is fond of saying, a really good diver can dive well in just about anything. But beginners can have significant difficulty with unstable equipment, and the combination of a big, fabric BC and soft or split fins leads to a lot of flailing around in the water, and diminished comfort. Make sure whatever you buy fits snugly, and that you can't shake the tank back and forth on your back very much. You've bought the Novas, and although I don't personally like them that much, they beat the tar out of floppy or split fins, in terms of helping a new diver stabilize himself in the water.
Go take your class and have fun, and come back and talk about major gear decisions
