Could I just use one interface? How would the dhcp server know which
address to give out? Does it find the info it needs in the packet
somewhere?

Basic template (based ISC's daemon):
shared-network LAN {
subnet 192.168.1.0 netmask 255.255.255.0 {
authoritative;
range 192.168.1.20 192.168.1.200;
# any other options you may want
}
subnet 192.168.2.0 netmask 255.255.255.0 {
authoritative;
range 192.168.2.20 192.168.2.200;
# any other options you may want
}
subnet 192.168.3.0 netmask 255.255.255.0 {
authoritative;
range 192.168.3.20 192.168.3.200;
# any other options you may want
}
}
Since you're using three separate interfaces, you'll need to update your
init.d/BSD script to tell the daemon to serve all of them:
dhcpd -q eth0 eth1 eth2
