yes you can remove the pistons like you say, after you pull the heads. take note of orientation and location of each piston before removal.
if you rotate the engine by hand, you can individually inspect each cylinder wall as the piston goes up and down. look for scuff marks and the condition of the cross hatching. any compromising of the cylinder wall will point to some piston and/or ring problems that you would definitely want to address.

Piston rings and valves = yes, Valve guides and seals = no
A leak down test will test the cylinder's ability to hold pressure, not only is this useful for checking rings, but also valve guides and seals.
