I just used this step in the Sticky to make this picture.

But this process took about half an hour to get this effect. Is this the only way to do this or could I have done it in the click of a button?

In a word, no. The method in the sticky or the layer mask method I use are both time consuming but the're the only decent ways of doing it. Sometimes you need to spend a bit of time to get an image te way you want it. In the grand scheme of things half an hour is nothing, I've spent a good 12+ hours on a single image before.
 
There are alternatives i could suggest, but none as simple, and just as time consuming.

This process should seriously only take you 10 minutes.
I prefer to use the lasso tools rather than the brushes.
 
I usually create 2 layers and desaturate the top layer.

Lasso the bit i want to have in colour and cut it from the image.

How about separating the bits you want saturated/desaturated by using the colour selection tool? Use that and then maybe feather it slightly. Then select the inverse and desaturate using your favourite method (image > adjustments > desaturate is not the best way). Of course to be safer create separate layers to work on. :)

I used colour selection to do this -- made it very easy because it was practically a single colour:

I find the magnetic lasso tool in PSCS3 awesome for this kind of work, cannot remember if the same tool is in CS2, but its definately quicker than brushes.

You shouldnt desaturate at all. Use the action that come with Photoshop, in particular, convert to greyscale.

I find the straight convert to greyscale can be a bit bland; splitting to the individual colour channels and picking the best or blending two, using calculations gives a nicer effect, with more punch and definition....

Indeed, that what i suggested, its part of the standards action menu. It converts it to grayscale with the colour information, then allows you to adjust. Why make a new one when PS does it for you.
