Equipment:
1 - Cisco 1800 Router
3 - Cisco 3560 switches
1 - Cisco 3750 8 pt gig L3 switch
Physical Connection:
                                                       Cisco 3750 (8pt) advanced IOS services (10.11.50.245)
                                                                                   |
                                                               Cisco 3560 (10.11.50.246)
                                                                                    | (outside)
                                                          Cisco 1800 Router (10.11.51.250)
                                                                    |  (inside)                       | (?)
                                         Cisco 3560 (192.168.1.254)        Cisco 3560 (192.168.1.253)

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 (192.168.1.250) and F1 port (10.11.51.250).
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 192.168.1.254 10.11.51.254
      ip nat inside source static 192.168.1.253 10.11.51.253
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.
