Hi homegrown. Nice username.
Using phys sky & sky dome will give dark interior scenes due to the amount of light bouncing needed. This will also increase render times & noise levels.
I've found adding an emitter behind the camera helps to clear up interiors and help with the overall light levels.
Scene scale is important too, if the scale of your model is incorrect, you will get bad lighting solutions.
Studio is reasonably easy to use for views. F B L R T B will give all 2d views, press the 3D button to return to perspective or camera view, but make sure you have selected perspective or a camera from the little eye icon.
Splitting the windows to have multiple viewports is easy too. The top left of the viewport has window type & window option buttons. The window option button (second in from the left), lets you split the viewport. Each new viewport will default to a 3D view, so change as neccesary to the 2D viewport you require.
In 2D viewports right click & 'Look at object' & 'Center view on object' can help you to navigate easily. You can't rotate the view in 2D mode, just pan using ALT+middle mouse button.
Hope this helps,
Tim.
