I can't offer anything with respect to image "quality" but would suggest leaving photos at original resolution since this will allow you to crop and do ken burns effects (pan & zoom) within FCPX.

Import 16-bit TIFF's....you want the best quality prior to output...in my experience TIFF's are the way to go, JPEGs are fine if you have no alternative but why limit yourself? If your working in 10-bit (which you are unless you select 8-bit uncompressed which is pointless) then your JPEG's are already inferior, not that it'll show right away but again 16-bit TIFF's are better. Do your work in your photo editor and export TIFF's. I never import JPEGs or even PSD's or RAW files like CR2, or NEF....
