Where is the image Mapping tab? I am following this tutorial - https://www.youtube.com/watch?v=il7ajiCepus
(note at the 3:12 mark in the video is where the step I need help is) 
I need to put a logo onto a trophy I made in Blender. I am following all the way to the point where in the tutorial he says to switch the mapping to UV. But I dont see a "mapping" window like his. I have Image Mapping, but no plain Mapping window. I really need help to get this done. I am on a deadline for a championship football game film. I got the trophy all set, I only need to get it textured and get this logo on there and I can finish.
This is because you're using Cycles, but the tutorial you linked is for Blender Internal Render. You can switch to BI by going to the 3D view's header and, to the left of the Blender logo, using the combo box to select Blender Render.
