Also to answer your questions,
1. Yes the black & white picture is years old.
2. The google earth map points are often way off mark - I wouldn't use them unless the grid ref is either an 8 or 10 point ref. If you use the streepmap link on the page -
http://www.streetmap.co.uk/newmap.srf?x=498300&y=496900&z=3&sv=498300,496900&st=OSGrid&lu=N&tl=~&ar=y&bi=~&mapp=newmap.srf&searchp=newsearch.srf
it's much closer (plus the position is shown on the OS map).
3. The stones are on open land just over the fence to the east of the forest. The colour photos by me and Stu were taken with the trees just behind us.
In my post I wrote 'walk southwest along the track from the barrier at SE982975 then follow the line of trees that run southeast'. If you follow the track to Fitz's co-ordinates you'll be there.
Good luck!
