I have created few interactive maps using iMapbuilder, you can download a free trial from their website ( http://www.imapbuilder.com ), it comes with map templates which you can use instantly, and then add links, icons, clickable points to the map with mouseover text, etc.
The best way to understand any kinda sense of FLASH first u need to observe the tutorials specially those which u can find at their official site in tutorial section.
every one would give u his/her idea but u need make ur own mind and in own ways that's how u can learn FLASH better
