I got a set of Nvidia GeForce GTX 480's in a NON SLI motherboard. I was under the impression that I wouldn't need SLI to be capable of having 4 monitors.

Is this an incorrect assumption? Does my motherboard need to have SLI support to recognize both Nvidia cards?

No. Your motherboard only needs SLI support if you want to run the graphics cards in an SLI configuration (which would only allow you to drive 2 monitors, possibly 3 if you're using nVidia's Surround technology). If you just want to have two cards operating independently and driving 4 independent displays in an extended or cloned desktop configuration, then just put the cards in, hook up your monitors, and install the drivers.
