Sims 3 Store Stuff Question ~

Hi everyone,
I have downloaded all my games and custom content from G4TW and everything works perfectly, even through all the patch issues past/present. I download store stuff from G4TW mediafire but I'm a little confused, I downloaded the dec 2011 set, does that include everything or do I still have to download all the other files (i want everything that's on the store) that are in the december folder or does everything come included in the "set" ? Sorry if this is in the wrong area, or if it's been asked before ~ I apologize :3 <3 you guys for all my gaming needs. I'm just waiting on skyrim being available from you lol.

Thanks very much, I thought that it would be like the actual store compilation you know how they choose the best items out of the month and put together "must have items" into a set, but everything is included yay. It also makes me think of all the other months where i've downloaded everything and clicked install >.< I've never had any duplicated files though, so the game must delete them c:
