Well im not sure that any advise of how to do it would make it a lot easier, if you are not sure how to make any of it work. Because you are talking about several key functionalities that each could take quite a long time to explain in details. And most people assume that when people ask for help they at least have tried to solve it so they have something that doesn't work
So if I were you I would do some tutorials and read the manual on topics that include, "How to use keyboard", "How to work with animations", "Pin behaviour", "Collision detection", "Player control behaviours" and "maybe something about how to do AI" like the space shooter tutorial that comes with C2. it will cover most of these.
