Should I use pullups on each of my A/D converters?

This is my first use of the SPI bus.  I am planning to use 3 AD7793 24 bit A/Ds, an ADT7310 SPI Temperature Sensor, and a Keypad interface (SPI).  Should I use one (1) pullup per line in each device or just one (1) pullup at the PIC uC?  The uC is on a separate board connected to the A/D board.
