smellyharry,
I agree it seems like there's 100s of possibilities but having worked out the theme (3, 8. 4 as mentioned earlier) and the topmost and lowermost items, the range is much smaller. Good old Google!
re 32d: 31 is normal so the item in cell 32 has six letters (because 32 is 8 letters and 3 of those are below cell 32 so 5+1=6). Of the 8 letters, Joey's parent is 4, energy is abbreviated to 1 and the vessel is 3, the definition being the last three words. Do you know what replaces the clashes yet?
