new project

Hello everyone,
I'm very new to robotics and I'm trying to use stepper motors as a
means for propulsion for my project (it's a micromouse!).
I bought two of these motors a while back ago and I would like to use
these: http://steppercontrol.com/motors.html

I just e-mailed them to see if I could get a more detailed spec ***
since I can't find the part on the manufacturer's website and the the
store does not provide much info to begin with.

So I did a little research and I wanted to see if this solution could
work.
I will have a mircontroller sending pulses to a translator (Allegro
3967 : http://www.allegromicro.com/sf/3967/ )
The IC spec says it is a translator/driver but I can't really imagine a
soic package being able to dissipate that much power... should i get a
darlington array as drivers? I have one in mind already:
ULN2003

am i headed down the right direction??
