Downloaded an audiobook and can't seem to find it. Anyone help??

Should be in 'books - audiobooks'. You could also try 'recently added'.

If you've downloaded it on your iPad then you should get an Audiobooks option under the More button at the bottom of the Music app (the option won't appear if there are no audiobooks on the iPad).

I have an audiobook from iTunes Store. It downloaded, but does not show up under more. Only way to find it is to search for it by title from iPhone home screen. Ok with one book, but after I'm done how do I delete it from my phone ?

Also not good solution for multiple books.
