Congratulations!
I had similar last year when I bought my TF with 52k on the clock. I think the change periods are 60k or 6 years which ever comes first. Mine is a 2004 and had HG changed in 2010 so I changed the cam belt, water pump and tensioner over last winter. Given that yours was done 10 years ago I would definitely get it done sooner rather than later. Relatively little cost compared to a new engine and peace of mind.
