I'll be answering only the monobook logo question, as I wish for someone who's better at Wikia JS than me to answer the other one.

It's actually quite easy. Just upload a file under the filename Wiki.png. Ignore the warning that says that it already exists - It's from the shared repository at starter.wikia.com. The recommended logo size is 155x155, or at least that's what the shared repository version uses.
