? is what can I do to add some flavor to it?

What are you thinking? You can add different things if you want to, cold steeped coffee, vanilla. Typically hops, but not for an oatmeal stout.

and do you add yeast on a 2nd ferm or just transfer the clean brew?

I would think you should only add yeast if you have a really high gravity beer and need to finish out the fermentation with a strain that can bring it to the right gravity. Very doubtful that's the case here, so you can just transfer the clean brew and try to leave the most of the trub behind.
