it may be best to wait in the interim and see how it pans out. i sell in collectables categories and went through and changed everything into the correct categories and began adjusting all of the item specifics. 

i noticed instantly that sales ceased - so i did some searching and found my listings were showing up in the later pages of search results, when usually they come up in the first few listings under the keywords most people use. 

i strongly believe that whatever category the majority of people who sell the items you're selling are in, determines where you place in search results. i changed back to the incorrect category (the ones that everyone else has theirs in) and my items returned to the top of search results and got sales almost immediately. 

it's just a theory, but have spoken to other people who sell in the same categories today and they found the same thing had happened to them after they put their listings in the correct category and as a result, changed it back for the meantime.
