We have borrowed "Bloodied" and "Shift" from 4E.
I like Hero Points and give them out fairly frequently (RP awards and at each level).
I wouldn't change it, but changing to the "Full Round Action to Stand doesn't provoke" is an interesting idea.
They do have plenty of additional stuff in Pathfinders for Arcane Casters. Having played a Wizard for the first time since AD&D days, I found the Spell-like abilities x+int/day more than enough.
Our Oracle doesn't do much healing in combat and Channneling Energy lets him use his spells for other things. I don't think I would change it.
We run with very few house rules and I think it works well. I have made a weaker version of Breath of Life as a 2nd level spell to offset player death. I call it Cure Deadly Wounds and allow clerics to cast it spontaneously.
We use NPC Boons which I think are a cool element. Oh, and no Leadership Feat.
Hero Points - step 'em up a bit, more like 4E. So award more, and encourage their use a bit more. 4E used the "milestone" trigger to award an action point. I like the slight narrative control they hand to the player and the slight increase in flexibility/swinginess they offer.

Standing from Prone - I always hated that in any edition. Making it hard to stand from prone may be realistic, but I feel it locks combats down and reduces mobility, which are fun. So I might consider dropping the attack of opportunity triggered by that action.

Wizard at-will - I never liked the low-level wizard resorting to a crossbow. So I might consider giving wizards an ability mechanically identical to a crossbow (roll to hit, 1d8 damage) but it's an at-will blast of magic instead. Perhaps choose the damage type at creation.

The cleric in our party feels that having the healer use all his standard actions to heal isn't ideal. Perhaps allow some healing as a swift action, instead?
