What did You Include in Your First Service?

Our ST just rolled over 5k and it is time for the first oil change. I was considering changing the transmission & diff fluid too, like is done on BMW M cars. What is everyone's though on an extensive first service? What did you do other than an oil change?

changed the cabin filter to K&N
nothing else is needed but what ever makes you feel good is what you should do.
Well I did change to Mobil 1 also and rotated tires
