When you use the Xbox controller on PC

[Xenon808]

does it have the buttons shown on screen like the 360 version appears to?

Not constantly.

This video shows it. If you get against something to interact with you'll get an option with a blue circle telling you to push the blue button to perform the action.

The ammo hud in the lower left is in the shape of the directional pad, but it doesn't really look like the directional pad. It just reminds you which way to press for different ammo.

It switches to exactly the 360 interface when using the 360 controller; tells you to press the right buttons and has has the larger HUD as well, even the menus are changed to basicly the same as they are on the 360.
