I'm using Cisco Packet sniffer to  create a mock network. I have a 1841 router:
Interfaces: fa0/0 and fa0/1 and vlan1

Question:
To setup DHCP on the router, is it on the global config or one of the interfaces ie..0/0,0/1, or vlan1. why is the vlan needed on this router anyway.

VLAN 1 would only be needed if you also operate a switching HWIC in it. For "normal" use with just the on-board FE-Interfaces, just configure the IP directly on the interface and you're good ...
DHCP will work on that interface that matches the IPs you want to hand out (i.e., the DHCP pool)

DHCP is configured on the global config, not on a port.

VLAN1 is the native VLAN, and needed for proper function.
