These all sound like great upgrades to start! I love the Stillen Gen 3 intake and i'm actually about to install the Z1 High Flow Intake Upgrade Kit so I'll tell ya if its worth it:

Even though you're only in the 60K range, when I bought my 370Z I flushed every fluid i could think of; just so I know its properly filled and filled with synthetic.
Exhaust is a preference, but I didn't see headers or test pipes anywhere?
I'm sorry I don't know much about the Stillen pulley or AT cooler. In fact considering its a 7AT I'm not sure if you should do any transmission work - I'm currently going through the CSC mid-life crisis
so if it was a manual I'd be reccomending Zspeed - but congrats on the Z man, and good luck with her
