You'll probably do well to train in lightweight, neutral shoes. How much running do you do on dirt/grass/trails? If you are stuck in the suburbs like a lot of people, get a lightweight neutral trainer with a low heel-to-toe drop (like the Nike Free Run or the Saucony Kinvara, both of which have reasonable cushioning but a low heel-to-toe drop) for some of your easy runs on pavement, and get a thinner racing flat for your workouts and runs on grass/dirt/trails. Like other posters have said, watch out for flats that are too narrow for your foot, or just aren't comfortable. Rotating shoes is good because it switches up the stress on your legs, and keeping some reasonably cushioned shoes around for concrete is also a very good idea. Think of it as a portable dirt trail. Some people can survive running in flats 100% of the time on pavement, but a lot of runners just get pounded.
Also, getting some barefoot running in once a week is great. You can start with 10-15min in the middle of or at the end of a run, and work your way up to 30min or so. Not sure where in the country you are, but up north, it's cold and snowy, so you could only run barefoot if you had access to an indoor track. Otherwise that might have to wait until summertime. Good luck!
