In this case I would have to export out each damn frame and mod each one so that the background would be transparent. This would be difficult to do over the course of an entire amv, so is there an easy way to pull this off in less than an hour?

There really isn't an easy way to do this. AE is probally easier but this isn't what I'm here to tell you anyways.

I can make a box in the corner of a clip which can then be made transparent, but can I get that box [or shaped area] to move around showing the clip underneath? (without actually having either of my clips moving, only the transparent area moves).
To do this you first you need to create a grayscale image(It doesn't
have to be grayscale but if your just going for plain transparency grayscale is what you need.) in an image editing program. This image will have whatever shapes you make for the transparency may it be a box, circle, happy face, gun, etc (centered in the image) and will be larger than the video's resolution(ideally, doesn't have to in be unless you are panning the image with motion settings. That way when you pan you have enough image visible throughout the pan. (I hope that makes sense to you

)). Whatever 'color' (white or black) you decide to use for the background or the object/s doesn't matter because of an option called reverse key which I will explain in a little bit. (BTW Pure white and pure black will either be transparent or opaque where as grays will be translucent.)
Once you save your image into a format that Premiere can work with, import the file and tell premiere to keep it's aspect ratio. I believe you can do this by right clicking on the image, going to video options, and clicking maintain aspect ratio.
Next drop your background footage into a superimpose track. (Tracks 2 and higher in A B editing mode). Drop your foreground footage in the next higher track. Finally drop the image you made into the track above your foreground clip. Right click your
foreground footage, go to video options and select transparency. Click on the available transparency modes and select video matte( I believe it is called something like that I can't remember right now... It should be the last one on the list. Image matte may work in this situation also but if you see what I'm talking about select that first anyways)
Select ok to accept the changes and close the tranparency options window. While holding the alt key, scrub the timeline to preview the clip without rendering. If the right areas are transparent you can go ahead and apply motion settings to your image clip and have fun. If the areas you want transparent are opposite what your seeing go back into the
foreground clip's transparency options and select the 'reverse key' option and hit ok.

This is very simple. First go to the directory that you've been saving your project file to. You should see a folder titled something like 'Premiere preview files'.(This is the default location, this folder may be somewhere else if you manually changed it in premiere which you should know where if you did.) Next open that folder and delete the folder that corresponds to the project file's name that you used when editing your old project. All preview files associated with that project file are now in your recycle bin or completely gone if you used the shift key in conjucntion with delete to bypass the recycle bin.
