I know of the one on the radiator, passenger side of vehicle.  Where are the other two located?  
1995 LS 400.

I would like to flush the entire system but, for the life of me cannot locate the other two drain valves.

They're on each side of the engine block, accessible from underneath.  They should look like this:

Loosen the small hex (bolt) and the water should drain out the elbow.  When tightening, don't reef on the bolt; torque = 9 ft.-lb.

These sit in awkward places on the block. Not easy to see or reach on my driveway. 
Mine was really hard to get loose.  I succeded with one of the and it seems most coolant came out. I had to arrange  a crow foot tool to hold the part screwed into the block firmly while loosening the small valve screw. Some long extensions were needed.
