SOLVED! PIR Motion to trigger VS1053 MP3 Shield

It took me some time to get back to this thread because I have been busy with construction of my project. Sorry I didn't provide enough info, allow me to try again.
As of right now (09/17/2015) I am still building and starting to wire my props.
I have a total of three Arduino Uno's, L293D Motor Shield and a VS 1035B MP3 Shield.
I am building a Haunted Tree. It is about 12 foot tall, 3 feet wide. I am using phone wire to connect everything.

What I want this thing to do is:

  1. Play ambiance music while standing idle
  2. When motion is detected trigger one of 6 scares at random. Some scares are accompanied with a sound file
  3. delay about 45 seconds or so and reset.

The scares:

  1. The Crows: I will be running three mini servo motors inside crows turning their heads back and forth... I have two servos connected together to share the same movement and the third to run its own movement. I'd be happy with just random back and forth motions. I also have three red LED's to light the crows from above. I have a couple of sound files to play with the movement. I have all of this wired and ready to connect.

  2. The Falling Limb: I will be triggering a 12v solenoid for my "falling Limb". Also wired and ready to be connected. A sound file to be played with this as well.

  3. Dropping Spiders: I have two DC motors that are being used to raise and drop my spiders. Two spiders per wheel. I want them to rotate forward for X milliseconds, pause, then reverse. No sound downloaded yet but ideas are welcomed.

  4. Clown I have a battery powered Clown prop that sits on a swing. I am going to tap it's "try me" button to activate the clown. He laughs and kicks his legs. No external sound needed.

  5. Owl Hole: I have ordered a pack of 100 5mm LEDs. Max. Forward Voltage:2.0-2.4v,3.0-3.6V Max. Reverse Voltage:5uA
    I'll use some of those to back light a silhouette owl or some other creature in the trunk of my tree.
    Maybe flicker and/or flash.
    I have downloaded a few MP3 files of owls and growls. I haven't decided if I want an owl in the tree or a monster.

  6. Stump: I will be creating a stump with pneumatics. When triggered a monster or demon will pop out of the top of the stump. Sound to be played and LED lights flicker/flash.

So.... the questions.

  1. Is this doable?
  2. Will I need all three arduinos?
  3. Is phone wire acceptable to use to run most of this?
  4. What sketch do I use? (wow, this is almost me asking someone to write it for me. As awesome and great as that would be I am willing to do leg work on this, I'm just running out of time)
  5. Does anyone have any suggestions regarding the project to make it more scary/amazing?
