Three of the four mounts in my car were FUBAR, and the inserts were much cheaper than new ones. The third I had to replace. Just removing this weight shouldn't have much added vibration, but I suspect you will notice a little.

I did the LCA bushings without a press... definitely a PITA. I used polyurethane here too, primarily because no press is needed to install them.

Glad your timing belt went smoothly. The threads in my tensioner bolt were stripped (when I removed the bolt, the threads came with it) which made for a fun time for me.

As for the thunking... did you check over the rear suspension? Possibly the bushing/bearing at the top of the struts? I've got a thunk in mine that I haven't found either and I've done everything you listed as well.
LCA bushings without a press? Did you cut them out? I thought about the polyurethane, then decided to go with Moog stock replacement. Did you notice a difference with the poly?

How did you fix the tensioner threads? Helicoil?

I am going to get the car back on the lift and try to simulate the noise. If it is the strut bearings, it should be a fairly simple process. I am hoping it isn't the struts themselves. The KYB's are $350+ for all four. I'd also do the strut bearings as well. That is another $100... But, for the $6,000 I paid for the car, I don't mind some maintenance costs. Used Honda's hold their value well and I am trying to keep this car for a while. I just don't want to dump too much money into it.
