I want to add a second ip address to my fast ethernet port 0/0 on my cisco 2620. I also want to route all traffic from that ip to an inside IP. I have tried using ip address in the interface config, but it only replaces the current ip. How can I get both ip's on the interface? I also have no clue as to how I should then direct all traffic from the second ip to an internal ip.

The command you are looking for is:
ip address10.3.1.1 255.255.0.0 secondary
As for how to point adresses in certain directions I would suggest you look at route map commands.
route-map (IP)
To define the conditions for redistributing routes from one routing protocol into another, or to enable policy routing, use the route-map command in global configuration mode and the match and set command in route-map configuration modes. To delete an entry, use the no form of this command.
route-map map-tag [permit | deny] [sequence-number]
no route-map map-tag [permit | deny] [sequence-number]
Syntax Description
map-tag
Defines a meaningful name for the route map. The redistribute router configuration command uses this name to reference this route map. Multiple route maps may share the same map tag name.
permit
(Optional) If the match criteria are met for this route map, and permit is specified, the route is redistributed as controlled by the set actions. In the case of policy routing, the packet is policy routed.
If the match criteria are not met, and permit is specified, the next route map with the same map tag is tested. If a route passes none of the match criteria for the set of route maps sharing the same name, it is not redistributed by that set.
The permit keyword is the default.
deny
(Optional) If the match criteria are met for the route map, and deny is specified, the route is not redistributed or in the case of policy routing, the packet is not policy routed, and no further route maps sharing the same map tag name will be examined. If the packet is not policy-routed, it reverts to the normal forwarding algorithm.
sequence-number
(Optional) Number that indicates the position a new route map is to have in the list of route maps already configured with the same name. If given with the no form of this command, it specifies the position of the route map that should be deleted.
Defaults
No default is available.

Usage Guidelines
Use route maps to redistribute routes or to subject packets to policy routing. Both purposes are described in this section.
Redistribution
Use the route-map global configuration command, and the match and set route-map configuration commands, to define the conditions for redistributing routes from one routing protocol into another. Each route-map command has a list of match and set commands associated with it. The match commands specify the match criteria—the conditions under which redistribution is allowed for the current route-map command. The set commands specify the set actions—the particular redistribution actions to perform if the criteria enforced by the match commands are met. The no route-map command deletes the route map.
The match route-map configuration command has multiple formats. The related match commands are listed in the section "Related Commands for Redistribution." The match commands can be given in any order, and all match commands must "pass" to cause the route to be redistributed according to the set actions given with the set commands. The no forms of the match commands remove the specified match criteria.
Use route maps when you want detailed control over how routes are redistributed between routing processes. The destination routing protocol is the one you specify with the router global configuration command. The source routing protocol is the one you specify with the redistribute router configuration command. See the following example as an illustration of how route maps are configured.
When you are passing routes through a route map, a route map can have several parts. Any route that does not match at least one match clause relating to a route-map command will be ignored; that is, the route will not be advertised for outbound route maps and will not be accepted for inbound route maps. If you want to modify only some data, you must configure a second route-map section with an explicit match specified.
Policy Routing
Another purpose of route maps is to enable policy-routing. Use the ip policy route-map command, in addition to the route-map command, and the match and set commands to define the conditions for policy-routing packets. The related match and set commands are listed in the section "Related Commands for Policy Routing." The match commands specify the conditions under which policy routing occurs. The set commands specify the routing actions to perform if the criteria enforced by the match commands are met. You might want to policy-route packets some way other than the obvious shortest path.
The sequence-number works as follows:
1. If no entry is defined with the supplied tag, an entry is created with sequence-number set to 10.
2. If only one entry is defined with the supplied tag, that entry becomes the default entry for the following route-map command. The sequence-number of this entry is unchanged.
3. If more than one entry is defined with the supplied tag, an error message is printed to indicate that sequence-number is required.
If no route-map map-tag is specified (with no sequence-number), the whole route-map is deleted.
