I can't speak to the setup required on PS3, but as for Titan HM: Try to land Succor right as Tumults start, and cast again as needed. Your other healer (ideally a WHM) should be helping here. Provided Titan doesn't have Virus/Antibody on him, put it on before Mountain Buster. Time Eye for an Eye to be on the tank during or immediately after Landslide in Phase 5. Sacred Soil on the tank for Mountain Buster (you can try to do Adloquium instead, but you may find this more difficult to time accurately).
