Who is the one person that controls the World's DNS?
Because there are multiple root level servers no one person or organization controls the DNS for the world. It is also a distributed system so this would not be possible.
When would a dns server contact a root server?

What hosts devices would you still need static addresses?

Is the internet centralized or decentralized?
Mostly the internet is decentralized, except for DNS servers. DNS servers are servers that your computer requests when you goto a website with a domain name to get the IP to connect to. There are several cover-all DNS servers, such as Google DNS (8.8.8.8) and OpenDNS (208.67.222.222). Although you could create your own cover-all DNS server, it would be really expensive and time consuming. If you want to use the internet completely decentralized, then use IP addresses instead of domain names. For example, wiki.answers.com's ip address is 67.196.156.63, but they are hosting multiple websites on it so it isn't configured properly to use a IP address.

How would a mail server on the internet locate the mail server?
Whenever mail servers talk to each other, they look for MX records at the destination's DNS. When a DNS server is setup for a domain and that domain has mail capabilities, their DNS server will have at least one MX record to denote which server handles mail. The root DNS servers for the internet denote the addresses for the SOA (start of authority) DNS servers for a particular domain.
Where can you find dns settings?
