going to disney for the first time: tips,tricks, advice please

There have been some big changes lately in the FastPass system which allows you to skip the line. They used to not enforce the return time window but now they do. I strongly suggest educating yourself on the system and leveraging it. Some rides you need to get FastPasses really early for because they run out early in the morning. You have a return window so you want to plan it out so you aren't running back and forth across the pretty large parks all day trying to use the passes. For instance, at Hollywood Studios the FastPasses for Toy Story Mania for the whole day is usually gone by 10:30 AM and the standard line wait is usually close to 2 hours. If you time it right and get there when the park opens you can ride TSM three times with hardly any wait.
