There is absolutely a non-confrontational way to do this. Call them. Tell them you have a few questions about a couple of points in the contract. Ask them what point 3.2 means, tell them you'd like point 4.1 can be rephrased to make something clearer, and that you'd like the non-compete clause clause in 7.2 to be limited in duration and scope, because the way it's currently phrased, it could be interpreted as signing away your right to work, and that's obviously unreasonable.

Be reasonable, and you will likely get most of what you want. If they are unreasonable, you're probably better off working somewhere else.
