It may not be the most helpful info but....I am currently a first year at UB, but I am in the MA program. The PhD requirements are more strict than MA, but I also did not have a good GRE score. I actually called the department before applying to express my concern. I was told that they look at your application holistically and that they do not weigh one component more than others. Based on that, I would say that your experiences are very valuable and should be the highlight of your application. Additionally, at UB if you do not get into the PhD but you do get into the MA program, you can reapply for the PhD, I believe after your second year. You have a better chance of getting in then and you can still complete the PhD in the same amount of time that you would have normally.
