Physics problem help

So, this last problem on my final completely destroyed me, and it's been bugging me ever since I got back home. Can someone solve this and show me the work so my soul can be at peace?

My physics professor called it a Gyroscope of Doom, by the way.

Suppose there is an L-shaped rod (think half of a square's perimeter), with a side length L and total mass M. The rod is attached to the z-axis at the origin but is tilted an angle T below the xy plane, so it makes some sort of a tilted letter 'V' when viewed horizontally. At the end of the rod is a disc of radius R and mass M, which is spinning at an angular velocity w. Gravity is acting on the system's center of mass (not given). In addition, a spring of rest length 0 and spring constant k is attached to the z-axis below the pivot of the L-shaped rod (makes an isosceles triangle), and its other end is attached to the L-shaped rod at its corner. The torque exerted by gravity and the spring causes a change in angular momentum that causes the gyroscope system to rotate around the z-axis. The entire system is viewed from a reference frame C', which is travelling in the positive z direction at a velocity v. What is the period of precession, Q', of the gyroscope system as viewed from reference frame C'?

The problem should look like this: http://i286.photobucket.com/albums/ll92/cb000/GyroscopeofDoom.png

Come to think of it, this problem might have seemed impossible at the time because I'd gone through 7 other problems and had like 30 minutes left. I'll also work on it again and see how I do without the pressure.

Edit: some of the symbols I pulled off MS word aren't showing properly. Let me switch them.
Edit 2: Switched the small omega with w and the big omega with Q. Also, theta has been replaced by...uhh, T.

Somehow the picture is just more complicated than your word's Lol.

The picture should summarize it decently enough. I'm trying to find the period of precession in the moving reference frame C'.
