Cisco Router NAT Configuration

What is the simpliest way to configure the NAT on a cisco router that supports the following: Additionally are there problems with the hosts traveling through a non NAT router before it hits the NAT Router (where NAT configuration is)

One core NAT router (that connects directly to the internet) and connects to 2 routers (e1 and e2) hosts are located on the backside of 2 routers (router A and B)  Hosts off of RouterA are on the 192.168.100.0/24, hosts off of RouterB are on the 192.168.101.0/24

There's no problem with translating traffic that originated on networks not directly connected to the NATing router. You'll just need to include those networks in your ACL that defines what traffic gets translated. It sounds like PAT is what you need.
