At that mileage, I would definitely do in addition, at the very least, the tensioner. It isn't difficult, not really very expensive, low risk if you follow the directions exactly, and I know that mine at ~83K was not nearly as strong as my new one. Interesting that you have no grooves on your tensioner arm. I did.
I'm not sure that color is indicative of the condition of the plastic; I cut open one of my old guides and it was actually not just a surface discoloration. My guess is that nylon (which actually contains water) dries out and oil replaces the water. But I still think that inadequate chain tension due to a weak chain tensioner will eventually break any plastic guide, old or new.
I did this job successfully, and I am definitely not a mechanic, nor do I claim to be one. But I will say that it is very important to do this job by the book, especially if you are not experienced. I know how you feel. It was like doing brain surgery on a family member. But, hey, who do you trust the most? Yourself!
Did you look at the tool rental section for the tools. I'm thinking of putting mine up there, because I'm not going to use them for at least 9 months - when I plan to get another car in addition to this one!
