Almost done, but have ground to a halt.
11 A. Mary Jane hugs arriving amazon? (6)
?a?r?t
(The 't' isn't 100% certain)
24 D. Nimble nude taking floor is this (8)
(The 'this' is italicised) ?n?e???d
(I can see 'undecked', anagram of 'nude'+'deck'/floor, but I don't see how it fits the clue).
Thanks for any help.
