You can use StarOffice (http://www.stardivision.com) or Applixware (http://www.applix.com) to read Microsoft Office documents on a machine running Linux.There's a photoshop-like program for Linux called Gimp (http://www.gimp.org). Since I don't use either Photoshop or Gimp, I can't comment on the quality of the program as compared to Photoshop.
