Here is my setup
two Cisco 3825 with 4 ethernet connection.
4 ISP connection
Router 1 - ISP1 and ISP 2
Router 2 - ISP3 and ISP 4
I will be using NAT and HRSP on both routers.
I'm having problem with NAT and I was wondering if anybody know
which NAT or PAT design I should be using?

For each internet-connection you need one route-map that matches the traffic that should be natted and the outgoing interface. Here is an example for dynamic outgoing PAT:
ip nat inside source route-map NAT interface GigabitEthernet0/0 overload
ip nat inside source route-map NAT-VDSL interface Dialer0 overload
route-map NAT permit 10
match ip address NAT
match interface GigabitEthernet0/0
route-map NAT-VDSL permit 10
match ip address NAT-VDSL
match interface Dialer0
