NAR Home Page, the base from which to reach all the NAR's Web information about Safety Code, certified motors, sections, membership information, Sport Rocketry magazine, and the NARTS pages with downloadable plans and ordering information for plan books, technical reports, and motor testing data.
The online NAR MESS form, for reporting rocket motor failures of any NAR-certified motor.
The online version of the NAR's Certified Motor List.
There is an online, HTML version of the rec.models.rockets FAQ, though whether it's updated as often as the one on Sunsite or the one posted periodically to the newsgroup I can't say.
Joseph Schmalhofer's Motor Dimension Page has tabled lists of every NAR or Tripoli certified motor, and is updated frequently -- you'll want a browser that supports tables to view this.
JimZ's Hobbies has a huge plan archive, currently including over 100 scanned plans for old Estes and Centuri kits and plans publised by Estes in their long-gone Model Rocket News newsletter. The plans are in LZW compressed TIFF format, but it's not particularly hard to find software than can read that and print it to exact size -- including MS Word 6.0 or later.
And of course one can't forget Rocketry Online, the biggest dedicated hobby rocketry site on the Web.
