2 days in Richmond, VA...what to do?

Hello, I'm going to be taking a vacation to Richmond, VA for just 2 full days in late October. I'm very into history, and I know VA is full of it! After doing some of my own research, I have decided to stay away from Colonial Williamsburg as I've heard that alone takes a full day, and can be quite expensive....here's what I'm thinking....Yorktown, Jamestown, Richmond Battlefield, and the Confederate White House....do these destinations sound good? Anything I should add or avoid to this? What about restaurants in Richmond? Anything I just HAVE to try that's unique to the area? Thanks a bunch!
