I'd recommend reading the tactical lessons in the Falcon manual, they are some of the best for any flight sim ever. After that, I'd recommend flying some missions where you just use one weapon only, such as a Wild Weasel strike with anti-radar missiles and no possibility of having to engage aircraft, for example. That way you can learn one weapon well; you can use the campaign to set up such a mission and give yourself an escort to keep the MiGs off you. After you have that weapon sussed, do the same with another weapon etc, etc. If you adopt that approach, you'll find it is easier to take everything in and learn all the different launch and radar modes without getting overloaded with learning curves.
