How much of the file metadata of files that I upload to Mega.co.nz encrypted (and therefore unreadable for Mega on the server)?
Are the filenames of files encrypted?
I assume that the file sizes are not hidden, is this right?
What about folder names, and folder structure?

An explanation of the MEGA cryptography can be found in the MEGA developer's documentation in the "Under the Hood" section.
From this, you can deduce:
File and folder sizes although not encrypted, will be obscured. That is, without knowledge of the file/folder names or structure, you can only guess the total size of the encrypted data.
