Congrats on your camera! I have the same model and my impression is that it's a great camera!

If you plan to use it at fast apertures perhaps 1.4 (AFs one) is better.
If you will use it at f2.8-4 or smaller, that get 1.8 one.
Edit: on that camera I would buy 35mm 1.8...
That depends. the 35 1.8 is a great lens in many ways but it's not some kind of portrait lens.
The 50 1.8/1.4 is a great short tele and can be used as a portrait lens on the dx format as well.
