Just make sure you get the versions for your paticular game setup. CEP should not be causing any problems with the mods though because it is for making recolors compatible with the Sims2. It's not a mod, it just enables the game to see any recolors that were made for the game meshes.
Can you provide a link or a pic to that texture? I think I know the one your talking about but I need to be sure. If it's the one I think it is, the mesh was removed by the creator(helllolo). That's the only blockfoot mesh I know of for the fit chick.
Not always, but what you need to do is get the Clean Installer from MTS2. That will allow you to install them without getting any files from the expansions you don't have.
This really isn't a mod, it is just the unlocked maids outfit from the base game. They have just fixed it so that it will show up in CAS without enabling testing cheats so that you can have a sim who dresses like the maid.
