It should be pretty straight forward as we've made the setup/configuration part much more intuitive in 12.9. Our product manager wrote a blog which may be
helpful as well... based off of TFS 2013 and Toad 12.8, so it's recent enough.... www.toadworld.com/.../toad-for-oracle-and-microsoft-team-foundation-server-tfs-integration-setup-and-example
If you have any specific questions as you go along feel free to ask.
Thanks,
