Newbie help

Hi guys I’m quite new to UE4 and don’t understand a lot yet but there’s a bunch of stuff I want to implement in my current uni project and don’t have a clue where to start so any advice would be great
-object highlighting and changing the colour once interacted with

-Using the mouse wheel to move and object closer and away from the screen while inspection

-Adding flavour text to appear while interacting with an object

-Applying a monochrome filter that can be toggled with a key binding

-having the camera only focus on the object during interactivity
