That's how I feel, I don't reel confident to post what I call a trick for fear that you guys will think im posting the obvious
Well I think it's time I posted a little something that helps me work.
For all those out there with two monitors (very usefull if you have the right graphics card).
If you having problems animating and it's all getting a bit complicated and you loseing track of what's going on. Select the Persp/Outliner view, then select your camera, then in the outliner view click 'look through selected'. As mhcannon said before you can tear off this window and drag it into your other monitor and change your primary monitor back to the Persp view (or whatever view you want).
What this does is let you have a whole monitor showing what your camera is seeing and leaves you your main monitor to work and animate the camera etc.
Hope this helps, I know it's helped me
