Welcome, I am from MN also, a bit further north though I am in the Brainerd area. I am pretty new to this also, I have my second batch in primary right now and my first batch I just racked to secondary. Hopefully they don't suck.
I got most of my supplies from http://midwestsupplies.com/
you are very lucky, it is just a short drive for you to get there. No shipping costs for you
