You basically do what you want. You should have several administrative functions available through the browser interface. You can set passwords, SSID's, WEP encryption, etc.... it depends on the router. What is it EXACTLY that you want to do ( please no general statements because when you log into a router, specifics become important).

Congratulate yourself.

Click on a tab.
Choose an option.
Read the FAQs included with the router.

Ask a vague question.

Since Apple seems to have created their own group called "Admin" and given them sudo privlidges via /etc/sudoers

you can edit that file with a text editor (as root) however i would suggest leaving it there. This directory gives admin accounts root privlidges via sudo commands so really there is not much reason to have the root enabled on your mac.
