All good stuff. Most of what you mentioned is work climbing technique so you may not get significant feedback in a rec climbing forum. Check out forums like
Tree Buzz
and
ArboristSite
to find a wealth of info on work climbing technique and issues.
Just a point on lanyard use. Majority of the time I'm attaching my lanyard at the same place on my harness that I'm attaching my main rope system. I use it as a second short rope system. It is excellent for positioning and is very comfortable to hang on as opposed to side D's and even leg rings. While using a chain saw in a tree, especially while performing a take down, attaching to side D's or leg rings makes a lot of sense, depending on the tree configuration and work positioning you're trying to achieve.
