PostScript isn't a raster image format, so I wouldn't expect Photoshop
to import it directly, although many image programs have a plug-in
(usually based upon Ghostscript), or you can use Ghostscript directly
to rasterise a PostScript file.

The usual tool for interactively editing PostScript files is
Illustrator. Also, I don't know if Acrobat can read PostScript
directly, but you can convert from PostScript to PDF with Distiller,
or with Ghostscript.

The advantage of operating upon PostScript or PDF, as opposed to a
raster format, is that rasterisation loses detail. This isn't an issue
if the end result will be a raster image file, but it can be
significant for hardcopy.
