Displaying a Text when near a item, then display a hud (Press 'E' to investiage) + Halo appear

Hello guys, i new to scripting and such. Can someone lead me on how i can make this possible?

Something like a investigation script, Like i have a item (Book) and when i hover my mouse and press LMB or E on it a text will display "A Book and a picture .." on the bottom then you press LMB or E again and a HUD displays of the picture on the screen.

Also, so i won't open many posts. Is there a way that i can make a halo active on the player with F but when i press F again it will disperser?

Thanks!
