raidz

I'm going to build a freenas server, would like to make sure what I can do with such magical and advanced zfs.

If I have 5 * 3TB disks in RAIDZ (12TB storage in total), now I am trying to add another 2 * 3TB disks to this existing array.

Q:

Am I able to do it without affect/touch any existing data on RAIDZ volume?
What about take away some existing disk? say take away 1 disk out of the 5 disks, assuming only very small portion of data exists on the raidz.
