Just two left and any hints would be welcome:
14A Old poer - the ancient mariner - an outstanding looker (6) ???E?E
12D Lots practise religion leading to salvation's beginning (6) ???E?S -
I'm assuming the last letter is "salvation's beginnings" and think it might be ASSETS, but can't parse ASSET as being anything to do with practising religion.
The second letters of each intersect.
