Rotate Vector get Target Location

I have a camera system setup (for an RTS) which consists of a Focal Point (Actor Location) and a spring arm with Camera.

I am trying to do custom collision for the camera using a Sphere Trace of Radius X from the Camera World Location to the Camera Target World Location (World Location after Camera System being Rotated)

I have the World Location of the Focal Point (Actor Location) and the Current Camera World Location, I am trying to figure out how I get the Camera Target World Location (Location of Camera after rotating Pitch/Yaw of Focal Point

I am also trying to figure out how to properly Offset a Hit Result Normal by X Distance in Direction of the Normal.

I am able to get an Arrow Component to point in the correct direction, but cannot figure out how to take the Normal result and apply it to the Impact Point Result to get an Offset of Impact Location in direction of Normal?
