I don't think anyone has said that the hints gave too much away. I think the puzzle is solvable without the hints, but they, or at least some of them, are probably necessary to confirm what's to be changed, otherwise the solver could be left with the anxious thought that he/she's stumbled across an amazing coincidence and missed the real thing.
Many above assure me that 33 is fine, so obviously it is. I've never encountered a clue of this type with this particular word order, so was rather floored by it. Apologies to Nod. One lives and learns.
