I'm currently a 1L (rising 2L) at UB. The application process really depends on the applicant pool, anywhere between 4-8 weeks (sometimes longer, if you are on the waitlist, they'll notify you). I applied on March 15th and didn't receive the acceptance until the very last week of May.
Do you know which Dean you will be meeting with? From my own experience thus far, all the Deans have been more than helpful. One of the reasons why I have chosen this school is because the administration seemed very approachable.
I see that you're also a non-tradition student (or so I assume). We have several non-traditional students in my year. Some people are in their 50's, and one guy is in his 60's. I myself have worked a few years before coming to law school. Most students, however, are coming straight out of college or worked for one year in between.
Please don't hesitate to contact me with any questions you may have.
