You list the DNS servers you want your DHCP clients to use to resolve 
hostnames. If you're running your own DNS server, even if only a caching 
server, I'd use that. Otherwise, your ISP's nameservers.

No, masquerading is for where the addresses on your LAN are not to be 
"seen" by the Internet. This would typically be when you are using RFC 
1918 private addresses for your LAN (e.g. 192.168.x.x). Whether your 
(external) Internet address is static or dynamic doesn't matter.
