Apart from the advice about the anti-seize (Finish Line Ti-Prep, Ritchey Liquid Torque, Tacx Dynamic Carbon Assembly Paste, etc.) there really isn't anything special you need to do to build up a Ti race bike. Just make sure what ever fork you go with has a rake that matches the intended geometry/ride characteristics.
That being said, both my race bikes are Ti frames paired with Reynolds forks, Ritchey WCS cockpits, Kryrium wheels (ES tubulars and SL clinchers), and Shimano drive trains. But this is mostly due to sponsorship deals.
