You might want to try my modding program. (in my sig) It started it's life as a viewer to do in part what you want. You can view a compontent and it will show all the details about it. A list of the required techs will be shown. You can also click on the required tech to see if it in turn requires any tech.

This is the best!
You can see what it will cost to research up to that tech level (including prerequisities) in low, medium and high tech cost!
It's an invaluable tool for me. I use it often when I play those PBW games that I really put my heart and soul into.
