If I was just starting out I would read this ebook:

it goes over the basics, once you have a basic grasp then FT is a wonderful resource for new information and how to get in on the latest deal,
many here will refer you to manufacturing spending as a way to boost your miles, please be warned that many parts of flyertalk are very friendly this section is not, only venture there is you have very thick skin
