Options when cloning to larger or smaller drive

When cloning to a smaller drive lets say, using expert mode is it always recommended to use the -k1, -icds, and -r switches? Does -k1 imply -r? Just asking because this weekend I need to clone a 2TB drive with possible bad blocks (Still functional though) to a 525GB SSD and I want to know what the best method would be. Only a small portion of the 2TB is being used.
Also what If I shrink the partition prior to using Clonezilla to something smaller then 525gb? Do I still need to use those switches?

Yes, if "-k1" is enabled, "-r" is implied.
"what If I shrink the partition prior to using Clonezilla to something smaller then 525gb? Do I still need to use those switches?" -> Yes, option "-k1" is required because it deals with partition table, and "-icds" is required because it deals with disk size checking.
//NOTE// Backup important data before you use Clonezilla. Just in case.

Hey Steven, thanks for getting back to me. So my steps would be shrink the NTFS partition so it's small enough for the target drive, run Clonezilla disk-to-disk clone with -k1 -icds, then boot up and extend the partiton. Anything I missed?
Also can after I shrink the partiton down, can I use ddresuce effectively as I have astrong feeling that there are a few bad blocks? Not sure how ddrescue will handle the large to small disk operation as there probably no -icds switch. Can you prove me the correct commands to do this with ddrescue as well? Trying to be prepared as possible.

" So my steps would be shrink the NTFS partition so it's small enough for the target drive, run Clonezilla disk-to-disk clone with -k1 -icds, then boot up and extend the partiton. " -> Yes.
I do not think ddrescue could handle the large to small disk well. Actually the options "-k1 and -icds" of clonezilla won't handle that well, either. It's always risky to use that because both dd and partclone are imaging tool, i.e. deal with the blocks on a partition, not dealing with the files on a flie system.

Is -k1 required when going from smaller to large? let's say from 500GB to 1TB?
Yes.
