and i want to encode a version without any black bars,

i have three questions:
1) how to crop and keep ratio aspect at the same time?
2) resolution will decrease when cut off all black bars, in this situation, i want to keep quality lossless at the same time, which encode mode to use is best? i personally tend to use CRF mode, and use CRF15, i don't know if it's right.
3) mkv file is 1920×1080i 29.97fps, does it need to do deinterlace? to get a 1920×1080p 60fps file.
