They only need to be installed anywhere an air gap is present like the top of a bay resi etc. Air vents can typically go anywhere heat is present whether you are heating or cooling there only needs to be expansion. It's also a good way to remove air because when water heats up it expands. Pressure will force the air out.

Again you are correct about the 90 degree fitting it is a bad idea. Typically pumps need 2-4 pipe diameters in and out. 1/2' tubing would equate to 1-2 inches. Optimally for MOST pumps 10 pipe diameters is best but often the space required isn't available. Most pumps are engineered for 2-4 pipe diams. Pump speeds directly affect cavitation. Please feel free to investigate it further if you don't understand.
