1 - Cisco 1800 Router
3 - Cisco 3560 switches
1 - Cisco 3750 8 pt gig L3 switch
Physical Connection:
                                                       Cisco 3750 (8pt) advanced IOS services (
                                                               Cisco 3560 (
                                                                                    | (outside)
                                                          Cisco 1800 Router (
                                                                    |  (inside)                       | (?)
                                         Cisco 3560 (        Cisco 3560 (

A few more details:  
The 3750 is running an adv IOS to support L3 routing.
The 3560 is just a normal L2 switch with a single vlan  
The Cisco 1800 Router is new out of the box with no special configuration except for the F0 port ( and F1 port (
The bottom two Cisco 3560 are actually redundant switches.  Only one is really communicating data while the other is in standby mode.  

My questions are:
1. How do I static NAT from the 192.168.1.X network to the 10.11.51.X network so that the rest of the network can it?
- I imagine its something similar to:
      ip nat inside source static
      ip nat inside source static
2. Since I am using two switches for redundancy can I just plug them into one of the interfaces (fa2-9), or would I just be able to run 1 switch because I have to use the fa0 interface?  If I can use the other 8 interfaces (fa2-9) how do they need to be configured.

This config has been KILLING me so any help is greatly appreciated.
