I can see the words on the screen, an the From, To, Subject and Date are all clearly in English. Just the content of the email comes out scrabbled letters and words.

Answer 1

Actually you can't.  When you print directly from iPhoto you will need to print to a 8 x 10 borderless paper size.  That will produce the card with a white border on each size which can be trimmed off after printing. This screen shot shows how the card will print on 8" x 10" stock:

This is because the stock size for the card is 10 x 7 and no printer supports 10 x 7 borderless printing.  These two tutorials describes how to print the card if you have a 3rd party image editor that can handle layers or have Pages from iWork: #8 - Printing a iPhoto Greeting Card and #8a - Printing a iPhoto Greeting Card to Standard Stock Sizes.
