I highly recommend the very affordable 50F1.8II lens, and also the 85F1.8. They are extremely fast, sharp, and very affordable, and great for shooting people.
If you aren't a fan of primes, many people recommend the Tamron 28-75F2.8 lens. It's very affordable, and has extremely good quality. I think it would compliment your kit lens very nicely.
If you would rather spend alot more money to stay with Canon, there is the very pricey Canon 24-70F2.8L lens. It's slightly sharper than the Tamron, but it's also alot bigger and heavier (and did I mention, it is pricey).
I leave the wildlife lenses to the others. I'm not experienced in that area at all.
