In fairness, Mubarak is causing the chaos, not the protesters. Do they control the banks? Do they control the police and pay people to attack others with petrol bombs? If Mubarak would just go, insecurity would not be as big a problem. Has Tunisia fallen into economic chaos and political disaster?
Seems to me the first order of business is kicking Mubarak and the NDP to the curb and establishing an interim government to plan a legitimate election. No doubt various opposition groups have various aspirations and objectives, but to accomplish the first step all of them need to be united. If Egypt can't oust the current regime, there's no point to anyone crafting a detailed political platform. The protesters might as well go home and just wait to be arrested and tortured to death for having unauthorised opinions.
