You can use PIM backup or SPB backup. If you ever ned them again you can restore them.
As for card, you need a MiniSD card. Most of use have a MircoSD card which has an adapter for a Mini and Full size. If you have stock set up then you need a cab to make the phone read SDHC cards over 2 gigs. I have uploaded it
here for you.
Drag that file to the phone then open it using File Explore. Follw the directions from there.
