As far as things for you to try, there's dd_rescue and photorec which will be included on data recovery live CDs. The most important thing is do not do anything that might try to write to a drive, including putting it in a device which will try to automatically open it. You want to make no changes. Your first step is to make an image of it in read only mode using dd_rescue or similar. Then you do the recovery on a copy of the image. You don't work with SD card itself to do anything but make that image.
