[3D] Having an object follow mouse (Star Fox like control)

I'm building a Starfox/Omega Boost like game and I'm not sure how to really go about two things, how to create movement/camera boundaries, as well as having your ship aim at the mouse/cursor. I'm not looking to have code written for me but I just don't know where to look? I'm writing it in C# and the only other post I've seen is pointing to Java. Any advice on where to find what I'm looking for?
