Do we need to know about angular vs. radial nodes and the formulas used to calculate how many of them an orbital has? If so, what distinguishes the two apart from eachother?

Re: Nodes

No. However it is important to have a good understanding of the what the shapes are telling you, which will then give reasoning to why there are certain nodes- places where no electron will be found- where they are. Remember that the pictures of the orbitals, as Dr. Lavelle said, that they are the math functions to where electrons may be found. Don't memorize, but understand what the shapes are showing, and then you will have a strong conceptual understanding of what the quantum numbers are actually describing.
