Yatsuki, the books you mentioned are good, but there are better books out there if you're just starting out - visit a flying school and see what books they use for teaching their students - these will be much more relevant. The FAA has a pretty decent book you can download from their site for free.
As for buying flight FX, personally, i reackon you should save the money and put it towards a trial flight or some lessons.
Goodluck.
