Build Help for a Support Cleric (3.5 & Pathfinder hybrid)

[Naedre]

My GM is about to start a Pathfinder campaign set is Forgotten Realms. I want to revive an unfinished cleric that I have from 3.5 into this game, but I'm having difficulty figuring out how to build a strong support cleric that stays true to my original concept. The GM is allowing feats taken in 3.5 to translate over, but im uncertain if he will allow new feats to be taken from 3.5 material.

Also note: House rule, with a spellcraft check of 20 + 2xlevel of the spell, you can recast a spell from an expended spell slot.

Character Concept: Nathan Ford from Leverage. My character blames himself, a rich merchant family, and Cyric (God of Lies and Murder) for the death of wife and child. After being unjustly exiled from his home city, he encountered a priest of Hoar (Minor God of Karma/Vengeance), and dedicated himself to bringing "justice" to people who the law cannot touch. For his own part in his families deaths, he has developed a drinking problem and a near-death wish, believe he deserves to die for his mistakes.

He primarily focus on tactical planning and support for his teammates, ensuring success by enhancing each party member's strengths. His prefered weapon is a warhammer (his gavel).

Mechanics:
2 Cleric/3 Human Paragon/4 Runecaster
Str: 10
Dex: 10
Con: 14
Int: 13
Wis: 18
Cha: 18

Feats (3.5):
1: Quicken Spell
Bonus (Human): Divine Metamagic (Quicken Spell)
4: Extra Turning
Bonus (Human Paragon): Inscribe Rune
7: Easy Metamagic: Quicken Spell

Explainations of 3.5 Classes/Feats not in Pathfinder:

Inscribe Rune is a crafting feat allows the storing of Divine spells in written or metal runes that cast automatically when touched on the person that touched them. Think brew potion, but for divine only, no spell level limit, and you can set traps if people touch it accidentally. My GM has ruled that touching a rune to activiate it is a move action. The Runecaster prestige class is basicly a Cleric (3/4 BAB, full divine casting, same saves) that gives up Turn Undead (Channel Energy in PF) for nice bonuses to the Craft Rune ability, including eventually having the ability to have runes cast x/day or permenant. These are both from the 3.5 Player's Guide to Faerun.

Divine Metamagic is a feat from Complete Divine that allows you to use (level adjustment of metamagic + 1) turn undead attempts to cast metamagic without a level adjustment. My GM is allowing this to work with Channel Energy charges in Pathfinder.

Easy Metamagic is a feat from Dragon Mag. #301(I think?), that reduces the level adjustment of a certain type of metamagic by one.

Human Paragon is a class that is 2/3 caster progression, 3/4 BAB, gives 6 + int skill points per lvl, and makes 1 skill a class skill (I'm planning on Perception), 1 bonus feat, and +2 to one stat. I needed Human Paragon to get +2 to Int to qualify for Inscribe Rune feat, and the extra skill points to qualify for Runecaster.

Planned in Pathfinder:
+2 Human bonus to Wisdom

Feats:
1: Quicken Spell
Bonus (Human): Divine Metamagic (Quicken Spell)
3: Extra Channeling ?
Bonus (Human Paragon): Inscribe Rune
5: Easy Metamagic: Quicken Spell
7: Skill Focus: (Spellcraft)
9: Extra Traits (+2 caster level)(+2 concentration) ?

15: Spell Perfection: (Heal) ?

His in-game end-goal is killing Cyric, or dying in the attempt. To accomplish that goal, he knows he needs to put together a team and a skill-set capable of killing a major god.

My DM might allow rebuilds/retraining of feats.

Any build advice is welcome. I am particularly concerned with feat selection, and which spells I can inscribe into runes to really help my party shine.

Thanks.
