If your last MSQ was Dressed to Deceive, then your current quest should be Life Materia and Everything.

These are all in Western Thanalan areas (Camp Drybone or Horizon/Waking Sands)
You've got a ways to go before you can get that quest and become a WHM (about 5? 6 quests?). You still have your first trial to do, choose a grand company.
