Oracle build archetype advice

[Letric]

This is the build I want to play. I have to take Constable at level 8 when I have BAB +6 to get Harrying Partners and use it as Bonus Feat from Tactician
At level 10 I can share this feat almost free with that Squad Commander ability.

Squad Commander (Ex):

At 3rd level, a constable can spend 1 minute laying out a plan to activate the tactician ability without having it count against his number of uses per day. The ability must be triggered within 1 hour of the plan being made, and the benefits last for 1 minute per cavalier level he has. The constable can have only one plan at a time, and if a new plan is made, any old plan is lost.

Meanwhile, up to level 10, I can use Bodyguard up to 3 times per turn for Aid Another, and my standard to assist allies with Aid Another or just cast a spell. Keep in mind from level 4 and on, my Aid Another provides a +6, because I have Helpful (from halfling), which grants +4 when I use Aid another.

1 Succor 1 - Feat: Combat Reflexes
1 Succor 1 - Perfect Aid (Ex): Bodyguard, Aid + 1
1 Succor 1 - Human: Skill Focus alternative racial trait: UMD - Herbalist/Perception/Diplomacy

2 Succor 2 - No feats

3 Succor 3 - Feat: Phalanx Formation
3 Succor 3 - Teamwork Mastery (Ex, Sp): TEAMWORK FEAT

4 Succor 4 - Perfect Aid (Ex): Bodyguard, Aid + 2

5 Succor 5 - Feat: Shield Focus

6 Succor 6 - No Feats

7 Succor 7 - Feat: Shield Brace

8 Constable 1 - Bonus Teamwork Feat: Harrying Partners

9 Constable 2 - Feat: Swift Aid

10 Constable 3 - Squad Commander > Harrying Partners online

10 Succor 8

Now, I have a couple of questions:

- Is Shield Brace worth it? I need 2 feats to make my reach weapon work with Shield. The idea is to get more AC, and eventually Benevolent armor to provide its enhancement bonus to AC when using Aid Another. Keep in mind, I'll have 14 DEX and Heavy Armor, but that's it, and I'm in melee range, behind my allies.
- Should I focus in UMD for the best support options? With my Curse (that gives +4 UMD at level 5, and makes it class skill), I'll be rocking quite a lot. This will cost me the Bonus Feat to make it Skill Focus option.
- Does my STR matter? I'm planning to make it 10 STR, since I won't have any feats on combat, makes no sense to use a 14 when I just need to hit 10 attack for Aid Another.

Then we have archetypes. I REALLY wanted to take this one Divine Herbalist but I can't find a way, because it replaces 1st and 7th Revelations.

Are there any archetypes I can take without ruining my current build above? How could I arrange this build to be useful during leveling and get this Archetype.

I'm trying to find a way to get access to Remove conditions, and that archetype is perfect. Also, Dual-Cursed seems to broken, and I'm not sure how much my DM will like it, I'll have to ask though.

I could also use this:

Spirit Guide to get this Wandering Spirit Tribe and I wouldn't have to multiclass to Constable for 3 levels, but I still need 1 level of something else to get +1 BAB and as many feats as possible, so at level 7 Oracle I have at least 6 BAB and pick Harrying Partners, which is when I get the ability:

At 7th level, she gains the spirit ability of her current bonded spirit.
