It's the other way around - relational psychotherapy is a form of psychodynamic psychotherapy. And yes, traditionally, the relationship is more important in psychodynamic therapy than in CBT.

I kind of like what I read about relational therapy, in terms of approach and focus - they work a lot with affects, which I think is an interesting area.

The therapist will talk, too. Especially in the beginning, when you are getting to know each other. My current psychodynamic T leaves very long silences and sometimes says very little, but previous Ts I've had have talked quite a lot. So it varies from one psychodynamic T to another.
