If I changed the category would it speed things up?
Absolutely not!
Submitting to additional categories in hopes of speeding up a listing is simply directory spam, it makes additional work for the volunteer editors, and it slows down everyone's time-to-listing.
It is somewhat akin to the person in the checkout line at the supermarket who sends their kids to stand in the different lines in the hopes that one can get checked out faster. Then dashes, cart in hand, from line to line in hopes of finding a faster cashier.
When you submitted your website you were instructed to submit to the single best category and one can only assume that you did so. You've already resubmitted at least once. Just be patient. If, after you are listed, (assuming you are listed) a case can be made for a different category, then an Update URL request an be made.
And if that doesn't convince you, let me give you the clincher: sometimes, when we end up dealing with multiple submission, we accidentally delete all of the submissions. It happens, and when it does, no one is very happy.
