Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it.

Home Network...
The following diagram shows an existing and proven to work home network layout. You may be able to use this in setting up your own network if you have the resources to accomidate this type of design.
Ultimately, Internet access is routed through the wireless router. However, DP1 is the actual DNS and DHCP server. DP1 and the router are the only machines with static IP addresses. The DNS server acts as both a caching nameserver and a nameserver for the local LAN (see Configuring a BIND DNS Server for more information). The DHCP server allocates IP addresses for both the wired and wireless computers and dynamically updates DNS to make the resources reachable by name (see Setting up Linux DHCP Server with Dynamic DNS Support for more information). If the wireless router were to crap out, DP1 is fully capable of taking over routing with a second network card and an iptables NAT configuration (see Configuring an iptables Firewall and Gateway for more information). If DP1 where to crap out, any of the other Linux machines can easy take over DNS and DHCP services. It's a fairly redundant system in many aspects. Make sure and check out Securing your Wireless LAN if you plan on having wireless support with 802.11b.

Can DP1 run with just one NIC?
Would it be a simple case of disabling DHCP on the router and setting up the DHCP on DP1 and all clients will connect to it automatically get an IP from DP1?
