Gorum's Divine Fighting Technique lets you Vital Strike on a charge with a greatsword, and you can trade a minor blessing to get it without a feat.

For the Samsaran spells, the paladin and inquisitor lists are probably the best option for a warpriest, but the swift action spells like "Litany of ___", Forceful Strike, and Dimensional Blade might conflict with the Warpriest's use of swift actions. Inquisitor does get some usually-arcane spells like True Strike, Invisibility, Heroism, and Stoneskin.
