Example code for Form Labels
http://www.evolt.org/article/Form_Labels/4090/15823/index.html
Form element labels aid usability by allowing users to click label text to select radio and checkbox elements. They are implemented using the <label for="elementID"> tag, in conjuction with the ID attribute of the <input> tag. Adding a style selector for labels lets you change the cursor (and other style accessible presentation characteristics) to indicate the clickable labels. This works in IE5+, and Moz0.9+. Older, non-compliant browsers will simply ignore the tag, making it fully backwards compatible.

Section 508 - (n) Electronic Forms
(The US Navy pages on how to code electronic forms)
http://www.navfac.navy.mil/section508/n.htm
The table of contents on this page has a link back to section 508 and also covers other topics of HTML including navigational links and application timeouts.
(*note* it appears these are instructional for the federal site compliance to the 16 requirements of Section 508. Each requirement section is stated with a summary and a link at: http://www.navfac.navy.mil/section508/default.htm
I found the information clear and easy to follow.
