What do you mean by "not completely work" ?
Extending the source class should be enough for what you're doing
(using a MemoryTrackListModel). You can look at the Last.fm radio
extension for an example of doing something similar. It's in the main
source repo, in src/Extensions/Banshee.LastfmStreaming/

I think you should download the image and save it in the right place.
See how it's done in the MetadataServiceJob class.
I wonder if it would be worth it to add a Metadata provider for Google
Music, to get cover art from there, like we already do with Last.fm or
MusicBrainz.

No, there isn't any proper documentation for developers.

I'd suggest you look into the "Banshee Community Extensions" project
on Gitorious :
https://gitorious.org/banshee-community-extensions/

If you add your extension in there, it'll be much easier for you, as
all the build infrastructure is already there. And it'll be easier for
packagers to make your extension available on various distros.
Just clone the repo on gitorious and add your extension in the tree.
When it's ready, just give me your gitorious id, I'll merge your work
in the main repo and give you commit access there.
