Need help with resizing and adding bleed to a PDF

Hey guys, I have a pdf that's sized, full bleed at 6.5 x 8.357 in and the publisher wants the following:

Pre-cut Page Size (including bleed):  7 5/8 (7.625) X 9 1/2

Top, bottom, outside edge bleed border: 1/4''

Inside (spine) bleed border: 3/8'' (.3750)

Cut Page size: 7” X 9”

Artwork size: Set within a 7” x 9” cut page, there should be 3/16" (.1875) white border on outside left or outside right edge and 5/16" (.3125) border on the inside (spine) edge.  Top and bottom edge borders will be proportional (they will end up larger I think).

So basically the original file is going to float in the middle of the bleeds listed above. Is there an easy way to do this in Adobe Acrobat Pro or do I need to (finally) learn how to use InDesign?

thanks,
