But, you may be able to automate some of the above steps with the 'export for web' feature.
The only way to save an 8 bit png from photoshop is to use the export for web feature:
: ''File -> Save for Web'' (Control-Alt-Shift-S)


But Photoshop refuses to save an 8-bit "indexed colour" image as a PNG... :(
Otherwise, Photoshop insists on saving a 24 bit image, with an alpha channel if you use transparency.
 
In general, from Photoshop, whatever format you save to, it is a good idea to use Save for Web if the image is intended for the web.
