You didn't say whether you're a service provider or just a 
regular end-user trying to run a corporate/business network.

If you're a service provider, yes, throwing active firewalls 
in the data path might be a recipe for disaster as your 
network scales.

If you're just a corporate business, then your thought 
process is quite common. Some folks may make the router the 
border while in your case the firewall is the border, and 
vice versa. The topologies can get very advanced or they can 
be basic.

But if you're a corporate network, you're likely on the 
right track if you think the ASA will solve most/all of your 
security concerns.

Cheers,

Mark.
