Low Mileage maintenance

2xtreme1

Hello guys,
I just wanted to ask a few questions in terms on maintenance on a Z which is kept at low mileage.
I bought my Z with 3.3k Miles last May 2012.
Now, about a year later, it is roughly at 6.7k Miles.

I've done a couple oil changes, but I am wondering what else should I consider servicing. I'm pretty clueless when it comes to maintenance, especially since I keep it low mileage. I am doing about 3k Miles a year.

Should I change out the break fluid soon? Power Steering Fluid? Etc.

( After running a VIN Check, the previous owner seemed like he only had the Z for like 4 Months before he sold it, he had it around Oct 2011, I bought it May 2012)

Any input will be highly appreciated, thanks!
