You can do this now in Project View by grouping your projects by their Next Review date. This will show you all the projects which you need to review in the next week, month, etc. Select a project, review it, then select "Mark Reviewed" from the Edit menu (Shift-Command-R) or toolbar (if you've added it to your toolbar), or use the Project inspector to enter a specific future review date (and update interval).

You can save this view as a Perspective to easily get back to it later.

Similarly I'd love a view where I can see the oldest available tasks, to make me decide what I should do about them.

In Context view, try grouping your actions by their Added or Changed date. Again, you can save this view as a Perspective to get back to it easily later.

(We do plan to improve Perspectives between now and when we ship, letting you change their titles, switch to perspectives in existing windows rather than always opening new windows, delete individual perspectives rather than deleting all of them at once, etc.)
