Time to shelve this for a while, because my final solve is 33d which is driving me up the wall. I know the superfluous word, but I cannot make sense of what remains. I am also struggling to find one other extra word associated with one of the across answers. I am distraught that Candledave found the end game straightforward, as that too, still eludes me. No hints please - just hoping the magic of posting provides the necessary enlightenment!!
