Gosh, it seems like there is too much in there for 4 1/2 days. Are you sure you couldn't save Universal for another trip? I would recommend a day at MK first with a character dinner either in the park or at a resort on the monorail.
The next day I would go to Epcot. Honestly a 1/2 day is not enough. Make a day of it and try to see Epcot at a leisurely pace. Make sure you take time to catch as many performances as possble. Eat a sit down lunch at the restaurant of your choice and have a counter service dinner. Stay for the fireworks show - it's wonderful.
On the third day, I would go to AK in the morning (a 1/2 day is okay though to really appreciate the park a full day is better), then either MK or Epcot in the afternoon.
Day four TL in the morning then either MK or Epcot in the afternoon.
I don't know if your 1/2 day is in the morning or afternoon. If it's in the morning then I would save it for MK. If it is in the afternoon then what about Disney Studios (MGM)? You just have to be careful because early in the morning there are not a lot of shows going on yet and in the late afternoon the last shows finish relatively early. But if you can go see Fantasmic which is the last big show of the night, then do so.
Of course all this depends on weather (especially in the case of TL) and your
MNSSHP (don't know where that fits into your trip - beginning, middle, end?). Also, sometimes you just don't feel like doing what you had planned for a specific day. Definitely consider spending more time at Epcot than you have allocated.
If your dd has never been to WDW, I don't think you have to plan a lot of special things because the whole thing will be special and sometimes if you plan too much you stress yourself out for nothing. Make sure you leave time for swimming at your resort. On the topic of swimming, there is a fountain at Epcot between Future World and World Showcase made especially for kids to play in. Bring a change of clothes for dd and let her play there while you and dh sit back and enjoy a beverage.
