Yes your 06 has the filter inside the bolt, and if you are unsure of its condition I would highly recommend you remove and inspect it. On my 06, I removed and installed a new bolt/filter with new washers. My thought is I will just inspect the bolt at every other oil change and replace if needed. However, a lot of people recommend to remove the filter and install the bolt again.
If you have a 17mm stubby wrench, removing the bolt is not difficult it is just time consuming (you only have room to turn the bolt 1/4 turn each time). This thread has some good information (http://legacygt.com/forums/showthread.php/remove-all-banjo-filters-222758.html)
I did not replace the bolt at the AVCS bolt, although from what I read it is much easier to access. That is next on my list
