After seeing what others have done with this set in the official forums, I ended up adding a few individual items to my wishlist (both the EA version and the spreadsheet I've been compelled to start to avoid buying things twice). I'll pass on most of the furniture save for one of the couches, one of the end tables and the desk, but a lot of the clothing seems to be pretty versatile, especially a couple of the men's tops. I can't say the same for the hairs of course, but they're certainly interesting so I added 2 of the 3 styles. I like enough items in the set to where I could justify getting the entire thing at 40% off vs. 50% which is my usual store purchase threshold.
The premium content reference is odd, not sure why they said that.
