Divine Strategist grants a circumstance bonus to caster level checks and concentration checks. It never actually raises your effective caster level, therefore would not affect spell variables based on caster level.

Theologians increase their effective cleric level only for effects related to their granted domain powers, not spells cast whether they be domain or otherwise.

The Strand of Prayer Beads which works once a day for 10 minutes. It is a large advantage, but it will run out.

The Incense of Meditation is also a great bonus, but requires 8 hours of preparation time, and the effects last for 24 hours. Again it will run out, and you have to know exactly when you will be running into trouble or the effect and money to buy it are wasted.

The last two items are useful, but a smart opponent would try to escape and come back later (for the prayer beads) or another day (for the incense).

I believe arcane casters have other bonuses and abilities that divine casters don't have, or only have with specific domains. Wizards especially can be much more versatile and prepared when going into a battle when they know what exactly to expect.

/edit ninja'd - serves me right for taking my time.

Weird Words is a supernatural ability. It is an attack, but it is not a weapon. Arcane Strike is used only with weapons.

I believe that Arcane Strike was intended only to be used with weapons or natural attacks that count as weapons, not with any spell, spell-like, supernatural or extraordinary ability.

As to the damage reduction, yes, DR would apply as you are manifesting physical damage (ie. the slashing, piercing or bludgeoning) supernaturally.

Sunder Combat Maneuver
You can attempt to sunder an item held or worn by your opponent as part of an attack action in place of a melee attack.

There is one way I know to get ranged sunder, with the Fighter archetype, Archer; and it only works with a bow:

At 3rd level, an archer can choose one of the following combat maneuvers or actions: disarm, feint, or sunder. He can perform this action with a bow against any target within 30 feet, with a –4 penalty to his CMB.

Apart from that, I don't know of any way to make a ranged sunder attack.
