Welcome to Flyertalk! There is a lot of info on here, and it is a lot to take in. Just keep in mind that there are both "beginner" and "advanced" strategies on here- if an idea makes your head spin you may have bumped up against an advanced strategy that will take more research and info before you truly get it.
The other thing that I remember being fairly disconcerting in my early days here- sometimes you will ask what seems like a straightforward question and people will start inquiring about what seem like unrelated details. That's great because sometimes there is a different way to accomplish what your end goal...but, being new, you might not even know the right questions to ask to find that strategy.
