what is your degree, hardware (electronics) / software or a bit of both?
Just from the tone of this thread you seem anxious, which I can relate to back when I completed my final year project. If you are hardware CocaCola has given great first step of Pick a NFC reader IC, study it in depth, study NFC in general in depth and design a circuit based upon that chip using this knowledge. the PN532 you mentioned has a highspeed UART. You will be able to get a bluetooth chip that will transmit over UART/SCI. I've used this LMX9820A - Bluetooth™ Serial Port Module before. Its an BGA package I was lucky to be working with a great Technical Assistant able to use solder flux and a heat gun to get this on the PCB for a prototype run.
If your answer before is that you prefer software and the above all seems daunting, as it does to be as I'm a softie, I'd use an Audrino NFC shied and bluetooth shield. Its not going to be tiny. Though you shouldn't have any hardware issues and you can focus on the software which will be a project by itself if your writing NFC, Bluetooth drivers for the shield.
