i have the broadband on fa0/0 and the metro e on fa0/0/0. is it possible that both of these interfaces are configured for outside nat and can the metro e be set for the primary?

Note you will also need to reduce NAT timers and few more twists not describe in the document.

Yes, it is possible. Note for true fastethernet performances a 1841 is not enough.

How would I make the metro e on Fa0/0/0 the primary? it seems that i have 2 overload statements when i pull out the metro E circuit i have to remove the overload statement for that interface to get the broadband cable circuit working.

Make a working config first. NAT timers it's a just simple self-explaining config.

The default static route with lesser weight.
