You could reference 'The Galaxy Song' from Monty Python's "The Meaning of Liff" for some quick answers. But basically,
You are moving on the Earth at roughly 40,000 km/day times the cosine of your latitude, so roughly 0.3 km/sec
You are moving around the Sun at about 30 km/sec
The Sun and you and me, and all the stars that you can see are moving at a million miles a day (18 km/sec) around the center of the Milky Way.
How do all these vectors add up? It depends on the time of day and year, but as you can see the speed of the Earth around the Sun is the fastest of the three.
It is possible to compute our velocity relative to the CMBR, but I don't know this speed off the top of my head.
