Two things you'll definitely want to do is get your PF up to 1x and pick up around 30 ranks in MIU. Maneuver attacks are the bane of pures and being 1x in PF will go a long way towards helping minimize their danger. The MIU you'll want because mana tends to get spent QUICKLY when you're hunting without a weapon and you'll want to be able to make use of whatever wands you find to help.

After getting those and 2x in Spell Aiming (trust me you'll want that, hunting solely with CS spells can be anything but fun in a lot of hunting areas), distribute whatever points you have left from dropping OHE and Shield Use either into lores that will help whichever spells you plan on using the most or into getting more ranks in Harness Power.

Once you make the switch, I'd suggest heading out to River's Rest and trying out Miasmal Forest (lesser moor wights, skeletal soldiers, bog trolls, and bog wraiths). My empath kicked major butt hunting there with Fire Spirit and gold wands at your level and it should be at least as easy for a cleric since most of their spells are geared towards hunting undead.

It really depends what you are trying to train for. You look like you are putting a heavy emphasis on chrisms and getting fogging spells at the expense of hunting ability, doubling lore is expensive and a swinger needs CM by your level. It'll still hurt your hunting ability if you keep that when you switch to pure.

These are a couple of fairly extreme builds but they show the things that are relevant to pure hunting at around your level.

A bolter looks something like this. Lore is heavy on summoning. Enough MIU to activate any wand anytime (though it was only really before level 20 that mana was a serious issue). Cleric spells at or not much above level yet. The advantage of bolting is that critters that are susceptible to bolts are very susceptible and its a lot easier to take part in group activities if you have an AS attack. If you are GoS you won't want to leave home without fire spirit.

A pure CS caster looks something like this. Primary lore is religion. Cleric spells to level+21 as soon as possible. The advantage is being rather more efficient for most like level solo hunting. The disadvantage is that CS efficiency drops off much faster when critters gain levels on you than AS efficiency does.

Kind of late chiming in, but if your cleric is Smite-aligned I can't recommend enough Rathboner's CS caster build and Starchitin's advice to go to the Miasmal Forest in River's Rest. Mana will not be an issue because you'll be using 302 nonstop. River's Rest is pretty much a cleric's playground until 67.

They hate you. As soon as you leave, they are all over the place.
