One thing comes to mind which seems confusing for a lot of people:
Fusion uses the word "background" for two different things. One is the tool "background", which does exactly what it says: creating a colored background. Then there are the inputs at each node: One is called "foreground" and one is called "background". What it really means is upper layer and lower layer respectively. To combine two sources you mostly need the "merge" node, and there you can select which one is on top by connecting it to the "foreground". If you have more sources, like your render passes, then you need to build a chain of "merge" nodes.
Hope that helps a bit.
