@PsychoChick966: It's not strictly necessary to remove your Sims3Packs but when you run into a problem, you should remove them before reporting to see if they are caused by them or not. With the last EP there was a problem with a lot of windows and doors and one had to updated those. This was due to the half walls.
To make it easy you can simply move the whole DCCache folder to your desktop and later put it back. This saves you the trouble of uninstalling and will also get rid of all sims3packs in your game.
As for the other things: It always depends on the mod. Some won't need updating (I tried NoIntro with the Patch and that works with no issue). There's no way to tell which ones will be a problem and which won't, so I recommend taking everything out and first try without on a new game. Then put them back one by one to see if they work or not.
If you run into ANY problem, remove the cc and try without before reporting anything.
