Hey RyanK, you're doing exactly what I decided to do... about a month ago! And that is go from winemaking to beer. First thing you absolutely must do is read John Palmer's book "How to Brew." There is a free, online copy that I read on the computer, my blackberry, wherever I had time. I really didn't do a thing until I had read it, at least through extract brewing (I"m not at partial mash or all grain yet).

Once you've read that, you'll be ready to start at least and know what equipment you think you'll need. I was able to use most of what I had for beermaking that I used for wine. You should be able to use your primary fermentr, which is probably a bucket. Mine is 7.9 gallons and that works. I also have a 6 gallon carboy that works as a primary for beer, but it's a little big if you want to use it as a secondary. It should be fine though.
I got myself a bottling bucket, a 5 gallon brew kettle, and a capper.... and that was pretty much all that I needed to get started. I'm also going to get a 5 gallon carboy so I can use it as a secondary to free up the primary for more batches.
As for equipment, I highly recommend either Midwest Supply or Northern Brewer. You're pretty close to both of them so shipping should be quick. I'd recommend getting one of their beer kits too for your first brew, or a Brewer's Best kit.
