I'd recommend setting up specific defined views for your journal folder. You should be able to filter based on all of the data and only display what you're looking for. You can customize it to show only the fields of interest. You may want to add a custom (user) project field. If you use the GTD Add-In this will be handled for you. The add-in also has a couple of custom views already defined.
In order to get totals you'll need to cut and paste directly from the view into Excel.
Journal really could be a great feature of outlook. Unfortunately, Microsoft hasn't really given it any attention, nor tried to understand how it should be used. A lot more of it could be automated...
Hope this helps.
