Which product?

Hi I am new to the adobe product set and am finding it a little confusing.  I have come from imovie and powerpoint .... so these amazing products are a big step up.  Finding my way around premier pro, sort of ok....I guess the more I use it the better I will get.  However, I use to create graphic animations (simple business line and text style diagrams) in powerpoint, then screen record the animation using quick time, crude I know, but it did the job albeit a little jumpy.  In order to achieve a seamless transition when importing into Premier Pro, I would like to use one of the adobe products, but am confused as to what is the best product to use for this, Illustrator? Animate? After effects.... Any help gratefully recieved.  Thank you in advance.
