The transmission, no, but it's going to put more wear on your clutch. I typically don't stress clutch longevity to new manual drivers, but closer gear spacing and a very short first gear will contribute to long clutch life. It's basically a set of brake pads between engine and transmission, and (oversimplified) the greater the difference in speed between the two when you let the clutch out, the more material you're going to take off the clutch.

Mine is still original at ~245k and seems fine. I know some vehicles need a clutch before 100k. It won't last forever even if you baby it, but just something to keep in mind.

I understand it's somewhat load dependent but yes, ballpark 2800rpm. I'd give that a shot.

I know it's not a new battery by any means, but it seems to work well and there aren't any battery codes, pending or not.
FE hit, probably more than zero. How much I can't say, but I find shifting sooner helps FE.

Honestly I found that to be the biggest learning curve with the car. It's very possible to finely control battery usage with just the gas pedal but you can probably expect to still be learning that months or years down the line. Even with a fully functional IMA, you can drive in stop and go traffic and never get a bar of assist or regen (or more of one and less of the other) if you're really precise with the gas pedal.
