The easiest way to move files in and out of Pages is with a DropBox account. You set up DropBox on your computer. Then get a DropDAV account as well, and associate it with your DropBox account.
Once you do that you can use the DropDAV setting to import and export files from Pages using the WebDAV feature.
DropBox comes in handy for a lot of other chores too, so it is worth getting the free 2GB account. DropDAV is also free as long as you are using the free DropBox account.
