rainlendar works pretty well. i used it for a while. I wouldnt use sunbird yet because it's still an alpha release.

as for website calendar, if you have hotmail, last i checked, you could use the webbased calendar they had.

edit: i was right, in the top tabs, "today, mail, calendar, contacts". it's pretty advanced. give it a shot! only problem i'd see is that if your net goes down, you'd loose access to your data.
