How many directions am I moving in while I'm just sitting here? Any idea of how fast?

I'm not really looking for precision, or discussions about relativity, but rather generalities.
I'm guessing that continental drift and the effects of precession would be negligibly slow.
But, best as I can figure out:
Due to rotation, I'm moving eastwards at roughly 1,600 km/h, around the center of the earth.
Then the earth itself is moving about 108,000 km/hr counterclockwise around the sun.
Then the solar system is moving close to 792,000 km/hr around the galactic center.
And the galaxy itself is moving towards the Great Attractor at about 2,160,000 km/hr.
What have I missed? Where the hell is the Great Attractor moving? Isn't the galaxy also moving towards another galaxy in the local cluster, while we both head towards the Great Attractor?
I'm sick at home with the flu and I can't get these questions out of my head. Maybe I shouldn't drink so much TheraFlu. If you can make a FPP out of any of this, then...uh...godspeed. (How fast is that supposed to be? In what direct--oh nevermind)
