Hi garskoci. If you want to stick with windows compatibility, your best bet is StarOffice, IMHO. It has filters for word docs, and 6.0 supposedly maintains the doc format precisely.
As for a calendar, I use KDE almost exlusively, and I found KOrginizer pretty intuitive. There are different views for daily,weekly and monthly calendars. Also, the to-do and notes are detailed (a bit too much for me anyway) and just might be wat ur looking for. Not sure about other desktop environments. I'm not sure what you meant by Access..do u need a db for a calendar program? wow, you must be pretty busy! jk
Hope this helps.
