in setting if you enable location services, camera, the location the photo was taken will appear in photos
in photos, you should see photos, shared, albums, along the bottom if you select photos you should be able to see the date the photo was taken and be able to select the year the photo was taken and location
in photos if you select a location a map will open showing the photos overlaid on the location the photo was taken
this will only work for photos taken by the device, it wont work with photos imported into your device album
you'll need a working wifi connection for location services to work on the wifi only ipad
I think most of the photo editing apps would allow you to rename a photo on saving
you could possibly create albums name them and save photos to them
