i have a multi-class healer (Oracle/Cleric). if i take extra channel does it applie to both
Extra Channel: "You can channel energy two additional times per day."
or can i take it twice and apply it once to each?
Feat Descriptions: "If a character has the same feat more than once, its benefits do not stack unless indicated otherwise in the description."
also can i use feats like channel revival and quicken channel buy sacrificing channels from opposite classes, why/why not?
Quick Channel: "You may channel energy as a move action by spending 2 daily uses of that ability."
"that ability" is specific to the ability you are using. So if you spend two uses of oracle channel, then that allows you to use your oracle channel energy as a move action.
Channeled Revival: "As a full-round action that provokes attacks of opportunity, you can expend three uses of your channel energy class feature to restore a dead creature to life as if you had cast the breath of life spell (Core Rulebook 251)."
That one is less specific, so I would say that as long as both of your channels are 6d6 positive energy, you could spend any combination of them to use channeled revival.
Most of these are assuming your GM rules that the Channel (Su) revelation is considered to qualify as the channel energy class feature. (Since the actual class feature is "Revelation")

SKR strongly implies that the oracle qualifies for these in several posts.

It work on both. If I take Spell focus Evocation and I am a MT it work for both Arcance and Divine list. If take Combat Casting and I am MT it work for both list.... AS RAW it work for both but you have 2 big weak pools.
Pool A Cleric 3(Base)+3(extar channel)+CHA MOD for #Dice equal to Cleric class Level/2+1... And Pool B Oracle 1(Base)+3(extar channel)+CHA MOD for #Dice equal to Orcale class Level/2+1
The easy fix is let the Oralce of life levels stack with levels of Cleric. Ie Oracle life with channel abilty 5 cleric 6 channels 7d6 for (3 cleric+ 1 Oracle)= 4+(CHA mod)+3 for extar channel feat= 7 time+(CHA Mod)per day. Pool that is not to big but dose level base healing or damage.

It depends.
For feats that increase "uses per day" abilities (extra channel, extra rage etc.) I would say you have to choose one class.
For feats that enhance abilities (metamagic feats, spell focus etc.), I would say all classes would benefit provided that they meet the prerequisites for the feat.
In short. I agree with Grick.

It work on both.
What does? And how?
If I take Spell focus Evocation and I am a MT it work for both Arcance and Divine list.
That's because Spell Focus works on spells from the school of magic you select.
It works on Sound Burst as well as Fireball because they're both evocation spells.
If take Combat Casting and I am MT it work for both list.
That's because Combat Casting works when casting on the defensive or while grappled.
It works on cleric spells cast defensively just like wizard spells cast defensively.
AS RAW it work for both but you have 2 big weak pools.
Pool A Cleric 3(Base)+3(extar channel)+CHA MOD for #Dice equal to Cleric class Level/2+1... And Pool B Oracle 1(Base)+3(extar channel)+CHA MOD for #Dice equal to Orcale class Level/2+1
If you're trying to say you get two extra channels for each channel 'pool' then you're incorrect, since Extra Channel says "You can channel energy two additional times per day."
Also, even if Extra Channel did grant you an extra two channels per 'pool' it only grants two, not three.
The easy fix is let the Oralce of life levels stack with levels of Cleric.
What is it you're fixing? And are you aware that would directly contradict the FAQ?
