No, each switch only requires one IP for management. This can be in any of 
the vlans, theoretically.

switch and each switch contains all 3 vlans must the uplink port be a

The port should be configured for 802.1q trunking. You'll define one of the 
vlans to be the "native" (or untagged) vlan. This could even be some other, 
completely unused vlan (e.g. vlan 100). Some recommend using the vlan that 
you're using for management as the native vlan.

Anyway, then the other vlans are just carried across the trunk. You should 
be able to limit the trunked vlans, if you cared.

Depends on the stacking technology. I'm not familiar with the procurve's. 

do not want to do any modifications on the workstations, so I do not thing

Correct, all of the workstation ports should be in "access" (or untagged) 
mode, and you assign whatever vlan is appropriate for the connected device.
