As someone else pointed out, you get the values from the manual.  The 
second cell of the IPIC interrupt specifier is the level/sense 
information (8 == level triggered, active low, 2 == rising edge).

No.  All QE interrupts are multiplexed over either IPIC 32 or IPIC 33. 
UCC0 and UCC1 just happen to be QEIC 32 and QEIC 33, respectively.
