You can use any pins you want. There are SPI examples in the SDK and the pin numbers can be configured in the code.

Based on the information on this site it looks like you can use "UART at any baud rate, I2C or SPI".

The DK specification including all the pin outs and characteristics are here -> infocenter.nordicsemi.com/index.jsp . If you are generally looking at guidance on how to connect wire an SPI device there is good information here -> learn.sparkfun.com/.../serial-peripheral-interface-spi. Give it a go and then come back with some specific questions.

Did you look at this? cdn-shop.adafruit.com/.../pn532ds.pdf At first glance it seems to include all the information you need.
