I've actually found Microsoft's built-in Help document on DNS to be the best DNS resource. It's extremely detailed, if that's what you're looking for. To get to it, first install DNS on your server and then go to the DNS MMC snap in, right-click the DNS server and choose "Setup a DNS server" or something like that and then a Wizard will come up with a "DNS Checklist" button. Click that and begin reading everything. It'll take you more than a day but you'll fully understand DNS and its integration with Active Directory when you're done.
I didn't do the same with DHCP, but reading a few Microsoft TechNet articles on DHCP helped me out.
