I'm doing more or less the same things as you guys. Rereading my application, and several works by the faculty, preparing to answer questions about my interests and how they might be fostered by the program. Since I'll be there for a couple of days, I'm trying to decide whether or not I should send any emails. I don't wanna create an unnecessary burden, but, just in case there are some people whom I might not get to meet while visiting, I am considering it.
Thoughts?
