Sounds like you have the list down! Maybe take a look at your tires to make sure they perform/grip when you've got the SHO tuned. Service the RDU fluid also while you are at it.
As far as TStat, you should go with what the tuner recommends or will tune for. LME does the colder 160, Unleashed does the 170 (may tune for the 160 if you opt for it). What ambient temps, how much traffic do you see in your daily driving? If you see heavy stopngo traffic or temps get above 100F regularly, you might want to go with the 160. Mind you, with either TStat, the tune may command the fans to come on earlier and stay on longer, nothing to worry about, just be aware.
