Dear Darkknight512,
usually for Arduino shields you get all necessary library software you need to program the shield.
If you want to communicate with MIFARE Classic cards you need a NFC reader which fulfill specifications for this card. Not all manufacturers fulfill the specs, e.g. the reader chip in the Nexus 4 doesn’t. To be always on the right side prefer readers with NXP chip sets.
