Essentially what you're asking about is storyboarding.
In other words, watch the show and cherry pick the stuff that you want and ONLY rip the parts that you need, deleting extra.
Once you have a rough idea of what you want for your video, you map out the key scenes that you need to match via storyboard. From what I can tell most people here do it in their head by previsualising the project as they work on it and trying to match that on the screen. No reason why you can't step into a more film oriented mode and actually write or sketch out your ideas. It works well for some, less for others.
Try also getting your lyrigs and mapping out all of your connections eg: guitar sting = gunshot. You'll find that your scene matches drop dramatically when you do. Doing a lyrical scene match will also give you tighter storyline.
And lastly, there are lots of ways to save space while editing; Via the guides you can use the bait and switch method where you edit using something fast and smooth like Mjpeg where each episode takes about 1-2gb for a high quality file, or even using the avs file and editing directly off of the vob files.
