Magic Wand not working

I am working with  the lastest version of Ps on a dell lap top. Despite the fact that what I am trying to do is rudimentary I am having myraid problems:

1) When I choose the magic wand I am given the option of watching a video or of learning more. If I choose to learn more I am told that I should choose "new selection" from the option bar but there is no such option. Nor can I seem to just choose the tool.

2) I have attached the dreamtime tear sheet. When I zoom in on what I want and choose the sign I want and either lasso or use the magic wand, I then under edit use copy. Then I go to my background and paste it but it only shows me the triangle of the sign, not the content. However if I go back and increase the selection to include the content of the sign not just the triangle, all of it becomes highlighted and yet I can no longer choose to copy it. What I really want to do is just extract the content of the sign and wonder if I were to magic wand just the content and use selection based on color range would that allow me to get the content. 

3) I seem to need to save this file before it will appear as a layer. I have attached the triangle jpeg which as it indicates does not have the content of the sign but only the triangle outline. 

4) Unrelated. When I open the background I want it appears in the middle of the work window with it's size indicated in "points" whereas I want it to fill the whole screen so I can work with it. Thanks
