Linux (mv or cp) specific files from a text list of files?
rsync --files-from=file_list.txt /path/to/source/ /path/to/dest/
Rsync has the added benefit over the cp or mv commands because it will automatically create folders if they do not exist.

Copying between lzo compressed BtrFS's: de/re-compressing?
Not really, and it comes down to syscalls. Have an example:
open ("tuppence", O_RDONLY) = 3
fstat (3, {st_mode=S_IFREG|0644, st_size=15, ...}) = 0
open ("/tmp/tuppence"...

Is it OK to copy files installed with rpm to another location?
Doing it that way negates most the the advantages of using packages.
Fix the package to put its files where you want them. That way if you use rpm to verify files it will checksum the files in use.

Safest way to move a mount point that is a parent of other mount points on Linux to a new physical device
If you bind mount a directory, then the submounts will not be bound. So create a dummy directory somewhere, and do

Then the contents of the /var/lib/...
