It's too bad you're on a student budget. I'd say replace everything asap. Even in the 3-4 years that I've been snowboarding, the tech has changed. Not to mention your edges and core have probably deteriorated. Maybe check out craigslist or something for the prices on 1-2 year old equipment.
I told my kids, "Someday, you'll have kids of your own." One of them said, "So will you."
