Enchanter Cleric Advice?

I made this build for Pathfinder Society, and just hit second level. I was hoping to hear some advice for higher levels if anyone had done something similar.

Human Cleric of Shelyn 2
STR 10
DEX 14
CON 12
INT 8
WIS 18
CHA 14

Domains: Charm (Love), Luck

Skills:
Knowledge (Religion) +3, Spellcraft +3, Diplomacy +5, Heal +8

Spells:
0 - Detect Magic, Guidance, Stabilize, Light
1 - Charm Person (D), Command, Bless, Protection from Evil

Feats:
Spell Focus (Enchantment)
Selective Channeling

So far I've generally been buffing or using command to disable a foe and using the "Bit of Luck" domain power to provide rerolls to fighter/rogue types. Defensively, the "Adoration" ability is fantastic, as most creatures need to make a will save in order to attack me.

I was debating either:
a) focusing on channeling, and picking up alignment channel, extra channel, improved channel, etc.
b) focusing more on enchantment, and picking up heighten spell and preferred spell to be able to spontaneously cast suggestion or heightened suggestion.

b) focusing more on enchantment, and picking up heighten spell and preferred spell to be able to spontaneously cast suggestion or heightened suggestion.

A question why not take it twice for suggestion and charm person?

And a suggestion: take a few ranks in linguistics to pick up some common languages, and figure on loading a tongues spell for when that doesn't work. If you are investing in suggestion then you'll want to be able to speak to them.

PS: Also I'd have gone with Luck (fate) over just luck.
