It depends if you are printing from Windows or Mac OS in terms of what you need to do. There was considerable discussion about this two months ago. In any case, the only profiles that will make any difference on a Windows machine are those that linearize the gray scale curve and you either need to use one of Eric Chan's profiles or make your own using Roy Harrington's QTR. MacOS cannot use any "color management" using Epson's ABW driver.
