That's a pretty good site for laser rigging -thanks for that, I can use that info too.
As for where to get spinnaker parts, that's a tough one but just doing a quick search brings up a ton of parts on eBay. If you don't mind shopping on eBay or Craigslist then you can probably get what you need.
I think I still have, somewhere, the original rigging guide that came with my (UK) Laser 2 (sold many years ago) but I think you can download it from the above site. I'm sure you can find the Vanguard version on the web too, but again I have that somewhere.
Assuming that you are not involved in any class racing (if you were you wouldn't be needing help here), there is nothing on a Laser 2 expect for the blades, spars and sails which cannot be purchased from a decent supplier of sailboat parts. If have specific questions about a particular part, let me know and I'll try to point you towards a standard part that will do the job.
Log in to NAlaser2 on Yahoo. Avram can hook you up with the rigging DVD. He has the correct DVD's for domestic dvd players.
I've miss-placed mine and need to pick up another, Doh!
As for NAlaser2, it has been really quiet! Bummer. But there is still a wealth of info re: the Laser 2.
