Your daughter is probably not tall enough (54" minimum) to ride Kraken, their excellent floorless coaster, but the whole family can enjoy Journey to Atlantis (water flume/coaster/darkride) and Wild Arctic (motion simulator and animal display). That's pretty much it for rides; everything else is either a show or a walkthrough animal exhibit.
Shows not to miss are Odyssea, Blue Horizons, Clyde & Seamore, and the Shamu Show. They also have some seasonal shows at different times of the year that may be worthwhile. The animal exhibits are scattered throughout the park, so do whichever ones appeal to you.
As I mentioned, you should have no problem doing pretty much everything in the park if you're so inclined. It's always a good idea to get to the park before it opens in order to beat whatever crowds do show up and to get the most out of your rather expensive day. Be sure to check the show schedules when you arrive to make sure that you time them correctly. The way they set up their schedules sometimes makes it hard to see a bunch of shows in a row, so you'll want to plan ahead. If you check their website a few days ahead of time, you can actually download the show schedule for the day you'll be there if you want to do some advance planning.
