1. Will I be able to create an image of the entire HD of my server and store the image on one of the clients (to burn it later to a DVD)?

Yes, we did something similar like this:
- start server with systemrescuecd
- enable a guest acces on one of your clients
- mount the client on the server with mount -t smbfs etc...
- use partimage on the server to directly save partitions of the server on client
- when you will recreate partitions for a new server remember to:
- - start again the server with systemrescuecd
- - mount again the client hd for images
- - use fdisk to re-create broken partitions (SAME SIZE OR A BIT MORE!!!)
- - use partimage to restore partitions
- - mount the renewed root parition
- - chroot to the new root partiiton
- - mount the proc file system
- - run lilo
- - umount proc fs
- - umount root partition
- - reboot and enjoy the recovery
