Press "menu"...in the picture menu, you can change the megapixel size in "picture size".

If the computer has the appropriate slot for your card, then the answer is yes.

You can adjust the quality in the menu under "record"

Touch the on-screen button(shows as a finger) to bring up the MENU, touch Image Size(two little squares) , select 1M (1280x960)

■ Number of pixels
Select a higher number of pixels for clearer
pictures when printing.

The higher quality will not degrade the prints, you can always reduce the size for printing, if you wish. (Although it shouldn't matter, if the printer is not able to print all the pixels due to limited resolution, it will downsize properly, anyway). The only drawbacks are, as you noted, increased size/storage requirements. I would shot always in the biggest possible size and with fine JPEG (no sense in using TIFF - the quality is not so different that you ever notive it). The reason for always using the biggest size is that you can later crop and have better chances at postprocessing. When "THE" shot comes your way, you don't want to accidentily store it in all the glory of 800x600 pixels :) (Switching sizes is a bad idea, you inevitable forget to switch the size back and shot an entire afternoon in the small size. Been there, done that, did not get the pixels back :)
