Swashbuckler Optimization

[LordErebus12]

Using Pazio material only, how would you build your best Swashbuckler of 10th level?

Rules:
1. No Alternate Class Features/Archetypes on the Swashbuckler specifically.
2. Required Ability Scores (you pick the order): 16, 15, 14, 12, 10, 8.
3. Must be Human.
4. Prestige classes/Multiclassing are allowed.
5. Starting Gold is equal to a 8th level character (33,000 gp).

What level is this being built to?
By no alternate class features, do you mean no archetypes as well?
How much money are you starting with?
Is multiclassing allowed?

please read the OP for some of those answers.

Starting Gold is equal to a 8th level character (33,000 gp).

Do you have a weapon preference? A rapier's the classic, and can get Dex to damage through Fencing Grace.

However, a dagger or shortsword opens up Piranha Strike, which is Power Attack without that pesky Str requirement. As a bonus, you can apply your precise strike damage to thrown daggers.

Ability scores:
16 goes into Dex, then add your floating human bonus on top for an 18. Spend your 8th-level stat boost to go to 19.
15 goes into Cha, then spend your 4th-level stat boost to get a 16.
14 into Con, not dying is good.
12 into Str so carrying capacity is not hopeless.
10 into Wis to keep that Will save positive.
8 into Int, the human bonus skill point will make up for it.

Level 8 is about where Piranha Strike surpasses Fencing Grace in raw damage, so let's got that route. This is based somewhat on my own PFS Swashbuckler.

Antagonize Use Diplomacy or Intimidate to goad creatures
Charmed Life +4 (5/day) (Ex) Choose to add Charisma bonus to save before roll is made.

Panache (Ex) Gain a pool of points that are spent to fuel deeds, regained on light/piercing crit/killing blow.
Piranha Strike -3/+6 You can subtract from your attack roll to add to your damage with light weapons.
Quick Draw Draw weapon as a free action (or move if hidden weapon). Throw at full rate of attacks.
Swashbuckler Finesse At 1st level, a swashbuckler gains the benefits of the Weapon Finesse feat with light or one-handed piercing melee weapons, and she can use her Charisma score in place of Intelligence as a prerequisite for combat feats. This ability counts as having
Swordmaster's flair (blue scarf, 1/day) As swt act, spend 1 panache to increase melee reach with light or 1-handed piercing weapon by 5'

Tactics? Use antagonize as necessary to make things come to you. Parry their attacks then riposte to get off-turn damage. You are not an archer, quick-draw and throw those extra daggers when you need a ranged attack. Use the potion of fly if something's outside throw dagger range.

Is there any way for a human to turn into a tiny creature without too much multiclassing? 'Cause I know someone that plays a kitsune that turns into a tiny-sized fox, runs into people's squares and just unarmed strikes them. He multiclassed with Monk so his unarmed does piercing damage. It is frighteningly effective. I don't know if there's a way to do this as a human, but if there is, I'd go with that. Something to do with Beast Shape II, maybe?

Edit: Turns out there is a way: Racial Heritage (http://www.d20pfsrd.com/feats/racial-feats/racial-heritage) and Fox Shape (http://www.d20pfsrd.com/feats/general-feats/fox-shape). I might go with that.
