Universal doesn't really require the same level of planning as Disney. The crowds are lighter, the lines are shorter and -- if you stay on site -- Express Pass + early entry into WWoHP pretty much negate the need for any kind of plan at all.
If you're staying off site, you could always buy an Express Pass if the crowds are heavy -- but many rides also have single rider lines that move nice and fast, if you don't mind splitting from your party.
Read the threads here, as macraven suggests. Figure out what you want to do. Then just go and enjoy those things on your own pace.
