recommend arduino with keyboard and display

Hi Guys,

I'm a software developer with no experience with arduino. I can code well, I've built computers etc but not electronics. I was hoping for some advice as to what to buy.

I'm planning to make a pseudo futuristic hacker costume for a christmas party. To give you some idea, like this or this. I want it battery powered, taking input from a usb keyboard and/or some buttons I can attach to myself somehow, and I want it to output to one or more displays (ideally one liquid crystal and one color) and/or a series of LEDs, and/or possibly a small motor.

How feasible would this be, and what kind of board/components should I buy?

Thanking you in advance.

IMO, you do not have enough time if you are talking about Christmas 2014.
