There is a lot of things to do and see. Do not buy tickets before your arrival to Prague. In the city center, there are several agencies (i.e. corner of streets Rytirska and Na Mustku neer metro station Mustek) which sell tickets and you have the best choice. If you really want to check the choice before your visit, have a look at these reliable pages:
Bohemia ticket
