If you needed to know how to get notepad, I really don't think you will have much of a chance in learning Torquescript, but if you really are committed to learning, I would suggest you start by changing variables within the default weapons and vehicles. Once you build up a knowledge of what each thing does, you can start to look at creating you own functions. I wouldn't recommend that you start making your own models until you know how code their functions, unless you already have a knowledge of 3D modeling. Although judging from what you have said, I don't think you do.
