To post an image click on the little camera icon in the format bar.
It is possible to create a train of letters following a path. You can use expressions, parenting, tie them to a null, do all kinds of things. When we see the image we can give you a solution.
So you want the characters/letters to move onto the screen and stop in that shape? Or something like that?
One of the ways Rick mentioned is pretty good for starters. Bring in all the characters as separate layers. Create a null object and draw it a path to follow. Then you can make all the letters children of that null object layer and offset them to your liking and they'll follow the path (if I'm not terribly mistaken)
That might be a bit rudimentry and crude, but it's probably where I'd start playing with this stuff.
