This is my first post so I hope its useful to everyone
First of all procurve switches as very simple to setup and manage. If you set it up correctly you wont have to touch it for years.
The key is planning it all first
Everything can be done from the command line with very simple commands I wouldnt even bother paying/using procurve manager. There is probably less than 10minutes config per switch for the setup you want.
As other people have said above I would make sure all the switches are running the latest firmware (dont forget they have dual roms so update both) and i would factory reset the switches to default configs, there is nothing worse than trouble shooting someone elses half configured switch.
For your setup I would create 5 basic vlans to get you started you can add extra ones if you like maybe for future use, it wont do any harm.
I would then use your 5400zl to route between the vlans and use the acls to restrict access to each one
Keep the vlan number simple and try and match the ip address range to the vlan number, helps quickly identify what vlan youre on e.g.
Vlan 10 CCTV ip address range 10.10.0.0/16
Vlan 20 Data ip address range 10.20.0.0/16
Vlan 30 - Phones ip address range10.30.0.0/16
Vlan 40 Servers ip address range 10.40.0.0/16
Vlan 50 - Switch management ip address range 10.50.0.0/16
Separate staff and student vlan if you so desire.
