Personally, as far as the mechanicals, I wouldn't touch a thing until you know you have to or you're ready for performance upgrades. Ride it for a while and get to know it. I have an '06 myself. I rode it for, at least, a good few weeks after break in before looking at mods.
My jetting was horrifyingly rich (which is opposite of what they normally are.) You can either invest in a JD kit or do it yourself (I think nminus1 has some tips...not sure if it was him or someone else.) In all likelihood, you will need to do some jetting changes to get it dialed in. Depending on your weight and riding venue/style, a very popular "first on the list mod" has been the suspension. Because I'm a fata$$, I resprung mine for my weight, but I didn't revalve (did the work myself.)
After that, I guess it would all depend on the type of riding you're going to do. No matter MX or woods, I would HIGHLY recommend radiator guards. Any of the top brands are fine. I went with Flatland and like them. The rads are expensive to replace.
From there...the sky is the limit. Find members with 450R's and visit their garages. That might give you some ideas of what the most popular mods are.
Congrats on the bike!
