I am also guessing I can even connect a device to the router that wont be its gateway? so as to avoid unneeded long runs of cable.
A DHCP client will transmit a "DHCP discover" message to try and find any DHCP servers on the network, any DHCP servers on the network able to giv out an IP will then back an "offer", multiple DHCP servers may respond, so the client will then send a reqeust to one of the servers that responded. When a DHCP server recieves this request, IP configuration in then transmitted to the host.

In answer to your second question, think of a router as two devices in one, the router/gatway/NAT section, and a switch connected to that. So, if you have two routers connected together, your actually connecting the two switch's together. So yes, device's connecting to one router will be able to use the gateway of the other.
