The first question is whether or not you need the AP to do NAT? If you were to have used a Linksys or other switch+ap with built in nat/router then you would already be covered.
To answer this question, does your provider give you a registered or unregistered address? If they give you an unregistered address, then you do not need nat. However, most providers only give out one address for home users. If that is the case, you will need to use NAT and DHCP on the AP to allow multiple machines access.
The best thing to do is configure the AP with an IP address and then connect to the web interface to complete the config.
Start here for guides as to how to configure the AP.
For your reference I am giving you the link to configure the 1200 series access point, Cisco IOS release 12.4 (10b) JA and 12.3 (8) JEC. this document will help you to configure the AP from the beginning .
