QT output is a mac-only maya feature, unfortunately so you'll have to go with the traditional method. Regarding your output question, you shouldn't have to create a separate folder. You know that when you set up a new project, you can choose "use defaults" which gives each part of the project its own directory within the project, right? Well, after you render out your images, and assuming you went into render globals and chose the proper naming convention and padding for your images so that it renders out with a sequential number (i.e., something like myrender.001.tif or myrender001.tif), you should just be able to open up AE and import (a Dialog box should ask you whether not it's an image sequence if Im remembering correctly...say, "yes" and it will import the whole sequence).
If you really want the images to render to a different folder in maya, create a separate folder on your HD and after you "use defaults" when setting the project up, change the path of the default folder the images save to, to the location of the folder you just created.
