Hi Ad,
Here is the link to a pdf file that has a range of pantone shades. Click on the link to download. They are all on A4 pages. You will have to take each page into Illustrator and lay them out to the width of your printer.
At Smart Graphics we have a print of this to double check. This can be for customers specifying Pantones or we just find a pantone shade that is close to where we want to be we specify that pantone in the RIP
Pantones Chart 
If you are working with a RIP then I advise all work is done in the RGB colour space. Usually the RIP can accept either RGB or CMYK and make all the necessary adjustments. RGB is a larger colour space and the files are smaller for archiving.
Another thing we do in Photoshop is to convert the image into the CMYK colour space, take the eyedropper tool and measure the CMYK percentage values. Armed with these percentages we look up the process Pantone book that you can get at any art suppliers. Our printer produces pretty accurate colours so this book can act as a reasonably accurate proxy eliminating the need to test print.
Hope this is of some help,
Keir
