Timing belt time

[Brian Link]

I finished the clutch on the coupe gt so I have time and back up
transportation to do the timing belt/water pump and pulley on the 200 20 V.
 Any advice or lessons learned before I tackle this?  Which brand of water
pumps are the ones to avoid? what parts to order besides belt, wp and idler
pulley?  I have the tool for the 10v motor to hold the crank, will it work
on the 20v?

tia.
