Yes.

Yes.

"Edit an ISO image" comprises the following steps.

 1. Mount the ISO image[*].

 2. Copy the tree of files to a read-write filesystem.

 3. Change the files in the read-write filesystem.

 4. Create a new ISO image from the read-write filesystem.

[*] IIRC, there are utilities that allow you to combine steps 1-2 into
    a single step: "Extract files from ISO image into a read-write
    filesystem".  But, I can't ever remember how to do that, so I
    just do the two steps.
