I'm going to break the rule by saying a 16-35 to cover both 14mm (it's really a bit too wide) and a 35mm prime.
Then for the other 2 lenses you can have a bit more reach without sacrificing the focal lengths in between. I'd recommend 100L for more variety, but 85L has amazing bokeh. This is for you to decide whether you want more background blur or more close up shots. Both are very good portrait lenses. As for tele, I'd recommend 70-200L, but that will overlap with 85 or 100, so if you want something light, 200 2.8 is a great choice. Or else 135L is also fine if you end up choosing the 85.
If I were to make the decision it would be:
because I don't really need the reach. I'd go for a 7D if I want to shoot far. Also, 16-35 gives you more versatility when you're indoors. You won't be going wide open if you're taking group shots anyway.
