Welcome Taybox! You are at a stage of multiboxing that each question you get answered will lead to five more questions. There are some great addons like Jamba that will do all you are asking, and there is a massive section on how to make the right macros for the right situations. What will help you most is to read the Wiki, all of it. Use the Search feature and browse the sections that will help you most (i.e. Addons, Movies, etc.).

Taking the time to do this will not only give you a good foundation for multiboxing it will also keep you from raising the ire of the veterans of this site who aren't very patient with those who aren't willing to do a bit of background work for themselves, especially since many of them laid the ground work that we all get to enjoy.
