Try creating, then taking, the Tournament Organiser test.
I believe that when you've passed that you will be able to create D&D Private Play events (and, if you contact WotC and get a public venue added to your account, public ones).
You should also be able to use the WPN Play Materials option to order WPN membership cards for your players, as they'll all need RPGA/DCI/WPN numbers for you to report the adventures.
You can also then sign up to D&D Rewards, here: membership.wizards.com/signup/signup.asp...
(you may have to ignore some out of date info there but it will get you signed up if you follow the trail, and scroll to the bottom of some of the pages!)
Note that you do have to report (or cancel) the events you set up, and you should get the RPGA number of everyone who plays, but they will not be displayed in the event calendar so no-one's going to show up on your doorstep!
(And if you've managed to pass the Herald Test already, you should be set up with most of the memberships you need)
If you have any other queries, let us know and we'll try to help! If your players plan to play LFR outside your group, do try to follow the rules and read up the info here (and ask questions) so that their characters remain appropriate and legal in the campaign at large. Oh, and I think that the advancement tracker got missed off the PDF of the latest version of the CCG. So long as, for every adventure, a player is tracking the name and code of the adventure, the amount of XP and GP gained (as noted at the back of each adventure), what treasure they took (no more than one permanent magic item per level) and their level at the end of the adventure, the precise format won't matter. There are some alternative versions floating around the net, I'm sure, or you can make your own. (Edit: Someone has uploaded the 1.8 version of the CCG to scribd for some reason: www.scribd.com/doc/13331729/LFR-Characte...
so you can grab the tracker from that.
Hope that helps!
