The command is md5sum. So you'd do:

md5sum -c checksum.md5

Where checksum.md5 is the md5 file to verify.

There is likely an md5 checksum in the root dir of the cd which you can
use to verify all the files on it with the same procedure as above.

To see what's in an iso file you need to mount it as a loopback device.
The command for this is:

mount -t iso9660 -o loop filename.iso /mnt/cdrom

Then the contents of the cd are available in /mnt/cdrom. They are
read only and if you want to you can copy whatever you want whereever
you want. If the above mount command gives an error you need to load the
loopback module with:

modprobe loop

To figure out how to actually burn the cd check out the cdrecord man
page and if necessary the cd writing howto.
