Warpriest of Cayden - two questions

[fof3]

I'm thinking of drawing up a Warpriest of Cayden. I'm torn between the sword and tankard of sword and shield style (using bashing finish) - is there a way to make a tankard a shield so that both can work?

Also, at higher levels how do you stop yourself from missing all the time? Our Cleric has Str 18 and can't hit for toffee - so a Warpriest would be the same except for the rounds where they have their sacred weapon (level rounds/day). I just played a Magus who routinely used Arcane Pool to play catchup on BAB - but he could do that all day long (and use two pool to attack touch AC). Assuming same Str and magical weapons a Fighter at 16th level will have about +7 to hit above the Warpriest, which is way too much to catch up on. How is it done?

In the case of the warpriest, use the Sacred Weapon ability and your various self-buffs.
