Motor Direction Control Help

Hi,
I am working on a dc motor control project using the Basic Stamp board. I am planning to connect two pins to a H-bridge configuration with two N-Channel MOSFETS (IRF510) and two P-Channel MOSFETS (IRF9520), and a small dc Hobby motor (1.5-3V with max current load of 1A). I will use the 5v power supply on the board. The transistor switches have continuous drain current of about 6A. I am not familiar with transistor switches·and was wondering what kind of current rating would i need to run my motor. Would these MOSFETS work or should I look for others. Any help would be appreciated.

See Gilliland's "The Microcontroller Application Cookbook", page 166 for a circuit that uses IRF511 and IRF9520. The motor is running off of a separate 12 volt supply, not the 5 volt on the board. Note that the 1K resistors to the +12 volts is a missprint. They should be 10K ohm.
