You need to 'float' the selection (e.g. detach it from the source layer) before you attempt to drag it 
around, otherwise, clicking and dragging will only move the selection 'mask', not the selected contents.  To 
float a selection you use the "Float" command from the Select menu, or I believe the keyboard shortcut is 
Ctrl+Alt+drag (the statusbar will change to read "click and drag to move selected pixels" when you get the 
modifiers right).

In the Colors (or was it Layer?) menu.  There is actually more than one way to reverse 'color polarity', but 
it depends on what colorspace/model is being used; the standard Invert command uses the default RGB space.

Under Image > Transform.  (If you image contains multiple layers, use the Layer > Transform menu instead to 
adjust a single layer at a time.)

Some programs you have to flatten the images into 1 image and then 
proceed to select a small portion of the greater image to drag, resize, 
etc to position next to the other image.

Mind your terminology.  Under the Edit menu you can say "Paste As > New Image" but then you wind up with two 
completely separate image windows with zero interaction between them; you're probably asking about "paste as 
layer" (also available in the Edit menu).  Alternately, when layer positioning is important you can do a 
regular paste, and while the selection is still floating go to the Layer menu and select "To New Layer" which 
will unfloat the selection and make it a new layer on top of the old one.
