You can do everything you want in the eBook editor. You do not need steps 1c-1d.
What I do is if the cover is not hi-res, I find a hi-res cover if possible. If I have to find a cover, I copy the cover to the clipboard and pust it over the existing cover using Calibre's editor. I reduce the cover to 1600 lines and then I recompress the images losslessly. I select to recompress at 80. That works rather well. It reduces the size of the graphics and keeps the quality well enough for eInk. 300px wide is not large enough (IMHO).
