Does the 70-200 limit you at times? I plan on getting both lenses but it's I'm not sure which one to start with.
Having 70mm as the widest focal length could be very limiting. In general, I'd agree with the recommendations to get the 24-70 II first. However, you listed outdoor portraits as your main use, and landscapes second - I think the 70-200 II is a better lens for outdoor portraits.
A suggestion, since you say you'll be getting both eventually: consider getting the 70-200 II and the 40mm f/2.8 pancake now. The latter delivers surprisingly good IQ, is f/2.8, and is relatively cheap. When shooting events, I often use the 70-200 II hanging from a Blackrapid strap attached to the lens collar. I keep the 40/2.8 in a pocket, and if I need wider than 70mm I swap lenses, leaving the 70-200 hanging from the strap and handholding the body with the pancake lens.
