I don't think that 1 action can be used for multiple feats/special abilites.
So you can't drop someone with a Power Attack, then Cleave into someone else?
You can't Spring Attack a Stunning Fist?
You can't Power Attack a Ride-By-Attack?
You can't use Exotic Weapon Proficiency: Whip with Weapon Finesse?
Don't be absurd.
Of course you can use multiple feats on 1 action.
If I wanted, I could use the bonus to the Bluff skill (from the Persuasive feat) to successfully perform an Improved Feint on an Orc, which triggers my Expert Tactician attack, which I choose to be an Improved Trip (performed with my leg, since I have Improved Unarmed Strike). This succeeds, giving me an immediate attack on the Orc while he's on the ground (at +4 to-hit). I chose for this attack to be a disarm--no AoO from the Orc since I have the Improved Disarm feat. Then, since the feint attempt was only a Move action, I can take a standard action--an attack. I chose to add +4 of my BAB to Power Attack the Orc with my foot (another Improved Unarmed Attack) and also use Combat Expertise to put +1 of my BAB into my AC, as a guard against any counter-attack from the Orc. On his turn he picks up his weapon and stands up, provoking two AoOs from me. I have Combat Reflexes, so I take both AoOs. My first is another Power Attack with my foot. The second AoO (from standing up) is a Stunning Fist attack that succeeds, triggering Expert Tactician again (and making the Orc drop his weapon again due to Stun). My Expert Tactician attack is an Improved Trip, dropping the Orc to the ground again and triggering the Improved Trip followup attack. For this attack I jump on top of the Orc with an Improved Grapple (no AoO), and use Improved Unarmed Strike to deal damage.
Yes, of course you can use multiple feats on one action.
