Improve portfolio grid image quality

Hey,

As far as I understand, the thumbnail images for the portfolio grid are generated automatically with width 732 pixels from the specified featured images, however, apparently, a very lossy compression is used resulting in the quality of the generated images that is not sufficient for my art representation needs. I found one adhocish way around this, which is to rescale the image down to 732 pixel width in photoshop and then add this as a featured image, then wordpress does not make any further compression and just shows that image in the portfolio grid (I tried this with two images to see that it works, but the rest are still automatically rescaled).

My portfolio grid page: *Login to see link

My questions.

1. Is it possible to add something to my child theme so that highest quality compression is used to generate the portfolio thumbnails from high resolution featured images and I do not need to manually create the exact resolution featured image in photoshop every time? If so, could you generate the code snippet?
2. Is it possible to have the width quality of the portfolion thumbnail image higher than 732 pixels, e.g. 1100, in the three equal width column portfolio grid layout as in my website? If so, could you generate the code snippet?
3. Could the outer left and right margins of my portfolio site be made narrower so that images in the portfolio grid appear wider and so high quality of the images can be appreciated? If so, could you generate the code snippet?

Thank you very much for you help.
