For the streets, I've had good experience with using Continental Gatorskin Tubular Sprinters with some Green Slime injected in as a backup. I got one flat, the first day I was on them, but it self sealed with the slime and all has been good for a long while now.

Regarding risers, I find that they're really great and comfortable being on them in the city. Get you up a little bit higher than with bull horns or drops, and yes, its completely reversible. Ride it and enjoy, Its good to hear about someone getting back in the saddle after a couple years out.
