You can make the map darker by lowering the ambience in the build game settings; or use the < > keys during test game. As far as scripting goes, you're never too young to learn something new
The community guide should be a good place for you to get started. It can also be beneficial to look over the scripts that come with FPS Creator and work on 'disecting' them, to better understand the more basic strings/actions. The fpi Edit Pad is also available for download on this board which is a very useful tool for scriptwork.
For future reference, this board isn't a request board, so "I need this" and "I need that" threads are usually overlooked or locked. When you run into some troubles with a script that you've been working on, you can post it here, and other members will surely come by to help you get it working.
