League of Legends (LoL) Question: Rune Page/Build for Thresh/Leona

Rune Page/Build for Thresh/Leona
Hi people. I like playing Thresh/Leona as tanky support, with a decent adc their combos dominate almost any bot lane, and they bring lots of utility/peeling/cc. The problem is that i'm poor in runes, and since they are similar champs, by the moment I would like to have a useful rune page for both (been using AP std rune). I was thinking in 9x Armor Mark, 9x Life Seal, 9x Scaling MR Glyph and 3x Armor/Life Quints. What do you think about them?
Should I change any or perhaps going with Scaling Armor Marks?
What do you think about Relic Shield on THRESH as starter? For some reason I find difficult to last hit with thresh and feel a bit poor with ruby crystal, so I pick ancient coin.
What should I buy on first come back on both champs? Should I rush sighstone or is it ok if I buy coin/relic upgrade+wards+ruby/boots/Rejuvenation Bead?
At mid game I try to sell Nomad's Medallion and get Face of the Mountain (I find more useful it's active), obviously complete sighstone, tier 2 boots, and seek for Iron Solari. I like Face/IronSolari because of their actives (lots of shields for team/adc). Is ok aiming for them first before any other team?
What's better as 5th item on both champs? Perhaps Ice Gauntlet or Frozen Heart? Sunfire Cape? And 6th? Obviously is situational. I don't really like Mikael's because even I have the reflex of making it useful, my adcs don't seem to take advantage.
Finally, what do you think about Braum? Is it smart buying him having alreadyLeona and thresh? Also, as other kind of supp I only have Soraka/Annie. I feel Braum is stronger vs poke duo comps than Leona and thresh and less risky in all ins, but nerfs are killing it's OP-iness on every patch.
Thanks =)

Don't underestimate Face of the Mountain. It basically gives an ally a
I don't recommend
^General support page. I use this 90% when I am the support
For
I usually buy the upgrade for my gold item before getting
Imo talisman of ascension's active is far better than face of the mountain's so I wouldn't change it if I got

As for Braum, I feel that ever since he came out, Leona has been slowly getting pushed out. Poor Leona.
