Hey guys this is a simple one but should be noted since it makes using Spaces even easier...in the Expose/Spaces prefs panel, assign one of your screen corners to Spaces. This will allow you to easily see the Spaces screen overview as if you opened the Spaces app or hit the F-key. I personally think it's faster than either one of those methods as well.
[robg adds: I'll always pick the keyboard over the mouse, but if you're the opposite, this will help. Also note there's a new active corner for Sleep Display, to quickly sleep your monitor.]
