Yes, know that the s orbital has no nodal planes, the p orbital has 1 nodal plane, and the d orbital has 2.

Yes. Also remember that using the fact that s has 0 nodal planes, p has 1 nodal plane, and d has 2 nodal planes, we can predict that f orbitals have 3 nodal planes.

It's pretty easy to remember how many nodal planes are in an orbital by looking at the L value in quantum numbers, it is the same as how many nodal planes there are.
