MEF is the primary extension mechanism for extending the editor. If you install the SDK, there are a few new project samples set up to create editor extensions, found under C# (or VB)->Extensibility. These include:

• Editor classifier – for providing syntax highlighting
• Editor margin – putting a margin along the sides of the editor, with arbitrary WPF content
• Editor text/viewport adornment – for putting WPF visuals into the editor

You can find overview documentation on MSDN: Extending the editor, and Editor extension points.

Some samples you may want to look at: editor samples on code.msdn.microsoft.com, a couple more on editorsamples.codeplex.com, and the source for all the samples I've written.

I blog about writing editor extensions. On there, you can find descriptions of most of the extensions I've written, along with more general posts about performance, design of the new editor, etc.

Questions posted on the editor forum on msdn also are answered by various members of the editor team.
