Blending is typically done at bottling, or very shortly before. You want the taste of the individual grapes to come through, not be muddied by fermenting together.
Well, I have been known to blend wines (in my case, commercial wines) after bottling. For a party, say, I have dumped a bottle of cab sauv. in with a bottle of merlot in a pitcher.

I already know the blend that I want and it is WAY too much of a hassle for me to keep the different varietals separate. I also use the same yeast strain for 90% of my reds. I simply dump the grapes together and ferment and end up with rather nice wines.
Yep, you covered it. You can do it before you ferment, or after. If doing it after, you should wait until the wine has cleared and aged a bit, so shortly before bottling.
I don't do large enough quantities to warrant separate fermentation of several batches, so if I'm blending, I decide what I want before hand and dump it all in the fermenter together.
