There aren't any disadvantages to use multiple layers. Multiple Layer Design is the point of using Photoshop. You can change elements of a project one piece at a time rather than single layer apps that once you make a enough changes you can never go back. In Photoshop, you can create everything in a Non-Destructive manner and Multiple Layers is a foundational feature for that.
Layers are pictures stacked one to another, Layers can contain transparent pixels so you can see through Layer above what is on Layer below.
Whenever I create a new layer on Photoshop, it's always created above the active layer. Is it possible to change that behavior and make it so that whenever I create a new layer it's created below the active layer instead? My objective with this is so that whenever I import an image it goes below the previous one and not above.

This is for Photoshop cs5. It may work with other versions but i am not sure. So beside channel (on the same line as layers) click path and down to the bottom (where create new layer should be) click on the create new path icon. Select your pen tool and draw a path around the desired object. After that, go back to layer and click on add a new layer mask to the layer that you create a path on, then the undesired background will 'disappear'. Hope this helps!
To unlock layer press padlock icon on top of layers stack on LAYERS palette, when padlock icon on right side of layer is gone do what you want to do with that layer.
To Flatten your Layers in Photoshop simply go Layer>Flatten. I recommend saving your image as a psd before you flatten so that you can refer back to your layers. Then flatten and save as a jpg.
