My first all-grain batch was, er, a bit hectic. I forgot to add my Whirlfloc tablet in the last ten minutes of the boil.
I know I can use isinglass for fining at room temperature, but my brew partner is vegetarian, so that pretty much makes me a vegetarian, too.
Can I boil up a Whirlfloc tablet with some water, let it cool, and add it to the beer when I rack to secondary?

Irish moss and whirlfloc need to be used during rolling boil, and they stick to the proteins. On the other hand, post-boil clarifiers, such as isinglass or gelatin stick to the yeast. If you use them, you should then force carbonate your beer. So it's "no" to both, i suggest you leave 2 weeks in the secondary and your beer will be clear as crystal.
Irish moss (half of Whirlfloc) is a kettle coagulant. In a roiling boil the seaweed is like a snowball, crashing into and sticking to proteins. It needs that rolling action to clump. If your fermentation is still vigorous then you may get some benefit, but I'm not sure what role temperature plays.
Leave it in your fermenter for two or three extra weeks and let gravity do it's thing.
