Even if you haven't done any research yet, if you can come up with a good idea for a research project with your advisor this fall, that's really all you need for a 1st year grad app, I think. A well thought out idea, plan, and literature review. They're not looking for results from you yet, except under maybe the previous research essay, but that will be mostly undergrad stuff anyway.
I didn't have any professors read mine either year I applied. I'm not a good example to follow in that regard =P
