A background on weather balloons: http://lowcountryaccompanies.com/info/air-meteorology-weather-balloons - Goes into the history of high altitude balloons, which started out as far back as the late 1800s for weather gathering purposes (can you imagine tracking a balloon with no radio and no GPS????)
Start here: http://www.ukhas.org.uk/. This is the website of the UK High Altitude Society, and they have some great, general resources. A lot of their members also hang out on the freenode IRC server in #highaltitude.

Useful links
http://www.hobbyspace.com/NearSpace/index.html - Another site with lots of useful links
http://www.eoss.org/ - A group based in Colorado that does balloon launches all the time. They have a LOT of useful information, including annotation for FAA regulations
FAA Regulation 101 - The FAA regulations on unmanned balloons (note these only apply to your project if it violates anything in section 101.1, or 101,7, but the latter is more vague so it's not a bad idea to follow the regulations in 101.33-39 anyway. Also note that a balloon that bursts at altitude is considered an independent payload cutdown device)
