Weather you draw it in 512, 256 or 128 doesn't really matter THAT much, it's the preview quality we are talking about, since the game can't handle anything above 128 (well, the servers wont accept it, it could probably take it no problem) using anything above that in your previews is lying to the customer.
As for detail, I can't comment on weather 512 scaled down to 128 or 128 has more detail in any objective way, because mathematically they hold the same amount of information, however compressing an image down like that distorts the over all image, you get bad lines etc, some textures look fine and the process ends here, I've no idea what darkjak works in, but generally if you work in 512 or 256 or anything else (I've done a texture in 1024 before xD) once scaled to 128 you should refurbish the texture and finish off the smaller, finer details, to get a sharp result.
Or just work in 128 to begin with.
Just because I have nothing better to do, here are a few preview images of something I did the other day, with lower, and lower resolution textures:
(WARNING, THE MAPPING IN THE FOLLOWING IMAGES SUCKS, DEAL WITH IT.)
Original texture source:

Note: I do not have copyright permission to use this, I'd cite the whole fair use education clause for this one :3
[Images]
Full resolution
Half resolution
Quarter resolution
Eighth resolution
And all stacked on top of each other:
I don't think the images need much explanation, they are fairly clear to the eye, the bottom gear has the lowest resolution texture, and even that is bigger than toribash's texture resolution, the top gear has the size I'd normally use for a texture in 3D.
Again, sorry about the bad mapping, [/lazy]
