Copy ICONs from PNG and put into PSD file

This is an extremely simple project. I have about 500 icons that are saved in 2 large PNG files.? I need each icon copied out, resized to fit in a 50x50 square, have the layer style applied, and then saved as a png file named like [login to view URL], [login to view URL], etc.? I have attached a ZIP file that includes the 2 PNG files of Icons, and a PSD file that contains the layer style, sizes,etc.? The icons should be scaled with proper proportions to fit inside the 50x50 square ensuring that the outer glow on the layer style appears correctly and isn't cut off.? The icon should be aligned to the center bottom of the square as showing in the sample psd.
