gonna do a home NL tourney for poker noobs- advice?

[bholdr]

Some of my freinds form my neighborhood have expressed intrest in learning how to play holdem- NL tourneys, 'like they play on TV', of course. They know that i play, and have been bugging me to teach them/ host a game. so i think i might do it this saturday.

I have chips, and will be giving away some of the crap i've hustled from online sites (my extra copies of ToP and GISH, maybe some KEMs, etc) to the winners. But, i've realized that i really have no idea how to run a good tournament.

Here's what i'd like to do:

-have a couple $5 tourneys over the course of 4-6 hours
-I'd like to include a re-buy with the buy in, to encourage aggressive, fast play
-most importantly, keep the game fun and freindly and provide an educational experience

So:

I have 200 red chips, 200 white, 100 black, 100 green. I'm thinking white=5 red=10 green=25, black=100, players start with 500 in chips and a rebuy token, start at 5/10 blinds to double every 20 minutes... how long should this take? suggestions?

Is there a good primer for NL that i can give out, like a one-page NL for dummies? link me?

along the same lines, is there a good set of home game rules available? link me!

Any helpful anecdotes, cautionary tales, etc would be welcome, as well as anything i've missed. Thanks!
