Our phones arrived today.
The Nilkin H+ tempered glass screen protector fit beautifully. It comes with a plastic protector for the back, which is about as good as what you can expect from a plastic protector. The only reason I put the rear protector on was because of how my wife's last case managed to scratch up the back of her phone.
The cases we got have a pretty good feel to them. Not sure how much protection they provide, but at least they don't add much to the bulk of the phone. http://www.amazon.com/Xperia-Terrapi...ywords=z3+case
