Apoll, I'm new to the series as well. As far as camera controls are concerned, I have found there are a multiple options for fine-tuning your view. If you haven't yet, read through the hot keys and play around with all the options to see what works best for you.
Case in point: I have recently started using the preset camera angles (number keys 1-9) to jump between a high-altitude, top-down and ground-level views, quickly. It certainly helps when I'm giving group orders to large formations, especially on big maps.
