The emails you get from Stars containing the tournament summaries can be loaded into Poker Tracker using the File > Import Hand Histories/Tournament Summaries window.
The first few tournament summaries will include the full details of each tournament (buy-in, fee, place of finish for all players, etc) however, the remaining summaries will include only a small summary and not the full details of each tournament therefore it may be necessary for you to manually request each tournament summary, one at time. Beware though that if you request your last XX tournament summaries from Stars, the information that they send to you probably won't be complete enough to load into Poker Tracker. Poker Stars has a nice feature that allows you to request a tournament summary without having to go through customer support (from the Stars lobby window, select the Requests menu option and select Tournament History.).
