It uses the MW2 engine, so of course the graphics are the same.
MW2 used the same engine that MW1 was made on!

Yessir, you just can't upload skins. The Upload option just sends it to Minecraft.net.
You can zoom - with the Camera tool selected, hold right-click and move the mouse up or down, or use the scroll wheel; with any other tool, hold middle-mouse or use the scroll wheel.
Look down at the bottom of the 2d/3d view for information on how to use each tool.
