We have a couple of threads here for folks going to WW.

I've been going since January 2011. You don't need any equipment except for the starter stuff - WW changed its plan recently so any stuff older than December 2010 is not correct.
I added stuff as I went along - I have a Wii with a Wii Fitness disk & board; I use the Resort. Both help me get exercise in while it's too hot to be outside.
You can do this. Go to the meetings for support & tips. Lots of water. Be active. :)
You will find your happiness again.
