That's only 71K in 7 years, I wouldn't worry about the chain for another 29K. What I would do though is invest in a set of new valve cover seals and open up the top and check out the upper rails. Amber color is still OK, dark amber or getting beer bottle brown then I'd replace the upper rails.
I see nothing wrong with trying the Bendix pads, but they might moan a little (they did on the 4.5).
What brand of euro lights are coming in? I am considering that upgrade, but not sure when. I might be interested.
