I wouldn't worry about wheels so much. Saddle, bars, brifters, fork, rear derailer, pedals, rear dropouts, etc will pay dearly if you don't know how to wheelie already. I'd get an olde roadie off CL for $100 or less, install BMX platforms and practice. Maybe start on the grass. Get used to the feeling of leaning back to far, save it by jumping off the back of the bike (platforms help greatly here).
