Sound FX for Animation Project

These are the sound effects I'll be using for my robot character:

• Car revving: http://freesound.org/people/manychefsbroth/sounds/151877/#
• Drilling machine idling: http://freesound.org/people/KeyKrusher/sounds/160702/
• Fast swishes: http://freesound.org/people/goldendiaphragm/sounds/119117/
• Metal crash: http://freesound.org/people/sagetyrtle/sounds/40158/
• Running up stairs: https://www.youtube.com/watch?v=WRVUHsEg3zw
• Squeaky wheel: http://freesound.org/people/Robinhood76/sounds/101877/

I'm not sure yet if I want background music, but if I use it, it will be minimal and comedic like this: "Marty Gots a Plan" http://incompetech.com/music/royalty-free/index.html?collection=034&Search=Search

Incompetech.com is a good source for free open source music. It has professional-sounding music for different themes made by composer Kevin McLeod.
