There are no such things as adjustment layers in GIMP, but in one of the 
future versions, much more powerful tools will be available to allow 
non-destructive editing.  You can do pretty much of what's done there though 
in different ways as mentioned on the page that Tim gave.  As to why the BG 
copy 2 layer in your page is b&w, I best quote that page itself:

"the top layer (Background copy) shows where we did a simple 'remove colour' 
and have de-selected the 'eye' so as to hide this layer."

The coloured seem to be effectively desaturated with one of the adjustment 
layers.
