Reach evangelist, simply because while summoning builds can be powerful, they stop being fun when they bog down the game - to help alleviate this pain you end up spending a bunch of time creating stat blocks for your won critters so you don't waste time figuring it out in the middle of a combat, or you pass the buck to your gm who will not thank you, nor will the players if you do it in the middle of a session. And truth be told there are ways to be rid of summons on the high end -- eh, different thread.
Anyway, I'd consider reach evangelist, just because you're a great support, and with so many buffs and heals being touch range, well, you get it. Heavy armor if you can afford it anyway, unless you have other plans for those feats that are demanding.
I'd also consider playing a tanky stone oracle were I you. Not as much spell versatility, but you get more of them. If you can control the center ground, and you're a spearhead (i.e. everyone stays behind you, or doesn't advance past your mark) you can really screw the battlefield up for non-flying enemies. Reach spells, heavy armor, defensive combat training. mix n match, but makes for a really good battlefield controller particularly a dwarf with stonesinger/magic resistance, and the stone stability revelation.
