Starting Graduate School-Need Advice

I am starting graduate school (MSIS) next week. If all goes well, I will graduate in May 2009. I was in the Healthcare industry for approximately 16 years (and accounting for about 5 years prior to that). I don't have any experience in IT. Can anyone give me advice on things that I can do now to improve my chances of securing a job soon after graduation? I have an interest in IT Security. But, I am willing to start elsewhere after graduation.
