If you're using VLAN's, *never* use VLAN 1 for anything.  It opens you
up to a lot of possibilities for VLAN hopping.

that's all possible.  Each VLAN interface is treated the same as a
physical interface, so you can enable DHCP server where desired, and
use DHCP relay on VLAN's where you want to forward DHCP requests to a
DHCP server on anther subnet.

The PowerConnects work almost identically to Cisco IOS switches, so
you should be able to follow this if you need any guidance on switch
