I have a S5 135u PLC with multiple CPUs, and want to use a single communication card. How do I configure Citect so as to select the CPU I want information from? 

The SIEMENS driver supports multiple CPUs in the S5 135u PLC. Go into the IO device form in Ctedit, and set the IO device address to match the CPU number. Thus you would type in 3 to access CPU number 3.
