Kahless,
You should not need to create Global Channels or Tasks to use your 9211A. In LabVIEW, you should be able to specify the physical channels and create the software channels programmatically. You may want to search the LabVIEW example finder (Help->Find Examples) for the Cont Acq Thermocouple Samples-SW Timed.vi example VI. It can be found under Hardware Input and Output->DAQmx->Analog Measurements->Temperature.
If you do wish to create Global Channels or Tasks, this can be done in Measurement and Automation Explorer (MAX). Simply right-click on "Data Neighborhood," select "Create New..." and follow the prompts.
Hope this helps,
