While I don't have a status report template, I do have a personal Weekly Review dashboard hosted up on Google Docs.
Here is a link to my GTD Weekly Review Dashboard Google Doc spreadsheet that I created. [NOTE: Conditional coloring of fields & fonts may not transfer if you export to Excel or other spreadsheets.]
The basic idea is to track when you do the individual items of a review by placing the date in "Last Completed" column. The spreadsheet will then make a calculation based on today's date, and give you a GREEN, YELLOW, or RED status. Most of the items are on a weekly (7 day) schedule, but some of them are on a monthly (30 day) schedule. Here are some links for more information on how to implement conditional coloring of fields for Excel, Numbers, and Google Docs. Feel free to customize to your own needs.
I started using this dashboard last summer when things were really getting out of hand at work. I was finding my timing for reviewing Weekly Review items to be sporadic with some items being reviewed several times a day to some slipping a couple of weeks or even a month between reviews. To keep sane, I adopted this dashboard for Weekly reviews (which I look at everyday) and also David Allen's My World Mindmap (which will be a post for another day).
The key for me is knowing what I am doing and not doing, otherwise I turn into a crazy maker.
