In order to freeze the motion of the subject a fast shutter speed is required. Outdoors in daylight it is easy to select a fast shutter speed (1/500th sec. or faster) shooting at or near base ISO (ISO 100) even with a slow lens. Indoors the ambient light level is much lower and requires increasing the ISO (resulting in more noise) and opening the aperture (smaller f/#) to get the fastest shutter speed possible for the given light level. The usual price of admission is a fast lens. If the stage lighting is excellent, your 18-55mm might work ok. The alternative is to add light by using flash. Unfortunately for your budget flash is usually not permitted.

It depends on the ambient light level at the venues you will be shooting at and your budget.

Again, the answer depends on the ambient light level and your budget. The Nikkor 35mm f1.8G AF-S (about $200.00) and the 50mm f/1.8 G AF-S (about $200.00) are optically excellent, should be fast enough for most situations, and are very budget friendly. To find out which focal length works best for your requirements; set the zoom ring at 35mm and at 50mm and decide for yourself. I suspect the 50mm will be the better choice since it is slightly longer. The problem with the Fast Zooms (constanf f/2.8 aperture) is they are all quite expensive compared to the 35mm and 50mm primes and they are 1 1/3rd stops slower. Good Luck and Enjoy your Nikons!
