grinditout,
At this time, there is no way to mass delete bulk emails. From your inbox view, you can swipe your finger from the left side of the header to the right as a slightly faster way to delete messages. If you would like to make a feature request for deleting multiple emails, you can do it here:

To delete photos from your iPhone library, it depends on how the pictures were added to the iPhone. If they were pictures you have taken on the iPhone, you can select the trash can icon at the bottom of the picture when you are viewing it. If it's a picture you synced from your computer, you will need to unsync those photos to take them off.
Hope this helps,
