Ok guys, now for my final question, which is more productive for EoC, coasting with engine off and clutch pushed in, or coasting with engine off and car in neutral? Talking about a manual here, not auto.

I do both and don't really notice a difference between the two.
When I've got clear road behind me I P&G between 55 & 35 in neutral with my foot off the clutch so I don't have to Fred Flintstone the clutch the whole time.
When I'm in traffic my P&G is more like 55 to 45, so the glides are shorter. I usually clutch it then, but even then I'm throwing it in neutral sometimes.

It should be a small difference, but neutral would be better. In gear with the clutch pushed in, you will be spinning more parts (clutch disk, input shaft, related bearings, etc). There is not a lot of friction here, so it's probably not a big deal either way.

The pilot bearing is intended to be used intermittently, so I would have concerns for long-term life of the pilot bearing if you regularly coasted in gear with the clutch pedal depressed.

Coasting with a gear engaged and the clutch depressed may be useful to bump-start, saving the starter and the battery.

If your coast is going to be relatively short pushing the clutch in would be the better choice.
A) Your going to press the clutch in anyways even if you wanted neatreal .
B) Why waste time then shifting it out of gear waiting 9.5 seconds then repress the clutch Put back into the gear when a simple press of the clutch is all thats needed, in the case of a short coast.

Once the clutch is pressed it disengages the drive from the gears, same as when in neutral. The clutch is only actively being worn when changing gears or first pressing it, not holding it pressed in.
