I ordered the Premium Package, although it is slightly different for the 335i. Nonetheless, I have used--and regularly do use--all of the features mentioned in your list. Not sure what CIC Integration is either, but I imagine it's probably some hardware component necessary for some of the features to work.
I think you have to ask yourself whether the features are something that you'd like to have, or can do without to save some money as lordg said.
I love CA for example, would definitely get it again even if it were a separate option, and although I don't absolutely need PDC I find it extremely handy in my tight garage.
