So I ran into multiple issue soldering up the perf board and decided to go with the PCB.  It took a couple of times to get the board this clean.  Currently the HI/LO drivers are powered by 5V from the arduino.  After testing with 5V power the driver and toggle each input  none of the outputs worked correctly.  I ohmed out all the connections and everything looks good so I figured I should read over the driver datasheet again.  And much to my happiness and chagrin, Vcc need to be greater than 10V.  So this shouldn't be a horrible mistake and I think I can use the 24V that is going to the FETs to power the chips.  I will update again after I am able to run addition tests.
