For H-Bridge 
I am using http://www.hvwtech.com/pages/products_view.asp?ProductID=68
for 1 robot. And 
This

if
for my bigger bot (3 amps)

You will need 6 outputs for the 1st Hbridge or only 4 for the 2nd 

------------------
5) I also have a need to drive a 12vdc motor (around 1A) using the PWM
(speed) and direction from an AVR.  Can someone recommend an H-Bridge
module or web circuit diagram resource?

BTW: My applications are personal interest, not production.
