A orbiting satellite stays over a certain spot on the equator of (rotating) Pluto. What is the altitude of the orbit (called a "synchronous orbit")?

Do I use T^2=4pi^2/GM x r^3?

yes. Pluto's rotation period is 6.39 (earth) days. You will also need its mass.
then how do i get the altitude after i solve for r subtract the radius of pluto?
yes, altitude=r-radiuspluto
