The build is below as follows, but I'm asking if anyone thinks that anything should be adjusted (Spells Known, Item distribution, etc). Our DM is giving us roughly 3 months of downtime, so I plan to use it fully to craft, retrain, exchange spells as needed.
Looking for advice/feedback/et al.

Your BAB should be higher. It should be +8/+3, and 9 STR carries a -1 penalty, so CMB would be +7 and CMD 22. Otherwise, I like it!
Thanks for the catch!
It seems like your DCs are being calculates as if you have greater and regular spell focus transmutation in addition to enchantment, unless I am missing something.
School Power (Ex): At 15th level, pick one school of magic. The DC for any spells you cast from that school increases by +2. This bonus stacks with the bonus granted by Spell Focus.
For the DC's.
Mythic Flesh to Stone > Mythic Disintegrate. Disintegrate in general is not a great spell. You also probably want Mythic Chain Lightning since that's your Magical Lineage spell.
... Admittedly, Fireball is objectively better to Magical Lineage/focus on, especially since its mythic version ignores resistance/immunity.
What are your Contingency plans?
We fight alot of constructs/incorporeal creatures, else I would very much likely use Flesh to Stone.
Contingencies to escape helplessness/Greater Dispel Magic on any debilitating effects/GreaterInfernalHealing if HP drops below xyz and the like.
Something else of a note, I also have a 16HD succubus cohort who I've turned into a skillmonkeyjunkie with the rules for advancing monsters and judicious use of Planar Binding.
Besides her, and a balor (DM let me take the Improved Calling Malconvoker class ability as a feat for +2HD on GPB) cooped back up in our stronghold, don't really have much else in the way of assistance magically (the party is an inquisitor statted for reach/AoO fighting, a warder who shoots the BSF's AC through the stratosphere, and an orc fighter/brawler that deals tons of single target damage.) So what should I be looking into for proper spellcasting supplementation?
Given the character's penchance for demons (He's a conscript in service to Nocticula) I'm actually considering spending a good chunk on ruby dust for a simulcra (Perhaps one of said Demon Lord (18HD, 9000gp))
Mythic Flesh to Stone > Mythic Disintegrate. Disintegrate in general is not a great spell.
I disagree; I think Disintegrate is a great spell, especially for a sorcerer. It's one of the few blasty-type spells that has several other uses besides damage. My sorcerer has used it for the following purposes:
1. Created a hole in a BBEG's fortress so our group was able to bypass several doors warded by symbol spells.
2. Destroyed a Forcecage that imprisoned one of our martials.
3. Destroyed the armor of a defeated graveknight to prevent it from reforming.
Oh, another note: Contingency is a 6th level spell, not 5th.
If you're fighting a lot of Undead I can see Flesh to Stone dropping in utility compared to Disintegrate.
I'm not sure I wouldn't rather have Spell Penetration in place of Piercing Spell and then Greater Spell Penetration in place of the standard. That'd give a higher general response to SR, and with Chain Lightning the difference is negligible even with Piercing Spell (Perfected Piercing Chain Lightning w/ Spell Penetration = +9 to overcome SR, Perfected Chain Lightning w/ Greater Spell Penetration = +8). That said, Piercing has nice synergy with your bloodline arcana... *shrug* I can see either way. Though if you plan to take Greater Spell Pen at 19th, ignore my rambles.
That was my general idea, maybe throw in Heighten Spell MM to crank up some of my lower level spell DCs, with a 38CHA, I've got lots of bonus 7/8/9 level spell slots to spare.
