Is there a shortcut to controlling the arranging of layers? Perhaps utilizing the the Keyframe assistant? specifically, if I had 20 layers over 10 seconds. The 1st was to start at 2 seconds the next at 2.5 seconds. the next at 2.75 seconds etc. so that the changing layers would accelerate exponentially over a set period of time.

You might have to use time remapping, with an expression to set the start and end frames based on the index of the layer. The start point would be at 2+(index-1)*.25 if the increase were linear ... but for exponential ... hmm.
Hopefully this would give you something to post on the AE expressions forum.
But you know, by the time somebody figures it out and posts a response, you might have been able to do it yourself, making an exponential curve by eye. Just a thought. 20 layers isn't much. :-)

once you get your layers evenly spread over the duration needed, you could precomp those then time remap the precomp, select the two keyframes and then use the keyframe assistant and choose exponential scale. that should accelerate the rate nicely.
but as far as spacing those layers out easily, i think you'd need a script that would look a the selected layers and offset the start points of those layers based on their index number....
i guess you could precomp each layer then drag all those precomps to the new comp icon, choose sequence layers to space them out... but i'm not sure how much easier it would be to have to precomp each layer...
