Well, their first unofficial meeting was during the Hush storyline. In Batman Vol 1 617; Tim is kidnapped by Jason Todd and used Tim as a "shield-hostage" until Catwoman appeared and helped Batman against Todd.

Their first official meeting was in Teen Titans Vol 3 29; when Jason breaks into the Titans Tower and takes all members down one by one. He leaves Tim until the end. They fought and Jason won the match. Todd wrote "Jason Todd was here" written in Tim's blood.

And that's all I've got....Robins first meetings as far as I know.
