Hm... for Canon system with this purpose I would go for:
Eventually new 70D(if it's like rumors say) or 7D. ~1500$
Canon 85 1.8 for outdoor portraits, Sigma 30 1.4 for indoor. ~900$
Canon 400 5.6 for wildlife/sports 1300$
Canon 15-85 IS for general purpose and landscapes. ~700$ (should be cheaper if it's kit with 70D/7D)
Some flash, diffuser and reflector for portraits ~ 600$
Maybe there is a gap between 85 and 400mm, you can add 200 2.8 for closer sports and some outdoor portraits.
