There are two standard approaches to find initial PID tuning parameters: open loop, and closed loop.  Which one is appropriate depends on your system.  Closed-loop is faster for a system with fast response, but requires that your system be able to tolerate some oscillation.  Open-loop works better in a slow but stable system such as a heater.  Search the web for "Ziegler-Nichols" and "Cohen-Coon" for information about these methods.  Also, the manual for the LabVIEW PID toolkit provides an introduction to PID tuning.
