Questions regarding new server with dual 73 gig HD's

Please bare with me, I am a bit of a novice here and these might be some dumb questions.

I recently acquired a dedicated server with dual 73 gig scsi drives. The partitions of the first drive are as follows:

Filesystem Size Used Avail Use% Mounted on
/dev/sda7 1012M 236M 725M 25% /
/dev/sda1 46M 25M 19M 58% /boot
/dev/sda2 9.9G 2.3G 7.2G 24% /usr
/dev/sda3 6.9G 535M 6.1G 8% /var
/dev/sda5 47G 26G 19G 58% /home

The second drive is simply:
Filesystem Size Used Avail Use% Mounted on
/dev/sdb1 68G 328M 64G 1% /backup

Here are my questions:

1. Does that partition scheme seem ok?
2. I have tape backups (40 gigs a night) so I don't really need the 2nd drive for backups. I do not have RAID on this machine, so that is out. What can I use the 2nd drive for? Can I host files like videos on it or will that cause problems with the server? If I can host files on it, see #3.
3. I can access the drive via SSH, but is it somehow possible to access the /backup via FTP? That way uploading videos to it is a snap.

I'm sure some of these questions are ignorant. Please go easy on me.

Thanks for any help!
