If you're going to hunt over the plot, shape can be very important. Just clearing a 2 acre field leaves a ton of open space for feeding deer to either bust you, or not come out during shooting hours. If they do, you may be looking at having no shot because of distance. Hourglass shapes are good for a number of reasons. First, the pinch is a good for the deer because they feel more secure. This also helps you because your entry will be harder to detect. It also may give you more shots because the field won't be as wide.
Don't skip it, just do your homework. Oats are great because they grow almost anywhere, and are cheap. Rye will give your herd a food source after a couple frosts as its more hearty.
My thought for holding off on clover would be to get a sample, and start amending your soil. Clover is a bit more sensitive to pH being out of range and it costs a lot more.
