Looking for advice regarding VLAN configurations

I have a cluster of computers that I want to stick on a VLAN for logical separation mainly, and another network of IP phones that I want on one because apparently having the dedicated broadcast domain knocks out intermittent echoes during voice calls. I've been banging my head trying to figure it out, which will soon be the topic of another post, but I want to first make sure that I'm not doing the work for nothing. Here's what I'm trying to do:

pfSense
+--------+
| LAN    |---[172.16.0.1]----[172.16.0.0/16]    Dell PowerConnect Switch
|        |                                      +--------+
| VLAN20 |---[192.168.0.1]---[192.168.0.2]------| VLAN20 |--[192.168.0.0/24]
|        |                                      +--------+
| VLAN30 |--+
+--------+  |                                   +--------+
            +-[192.168.1.1]---[192.168.1.2]-----| VLAN30 |--[192.168.1.0/24]
                                                +--------+
                                                Dell PowerConnect Switch

For each VLAN in the pfSense router an IP (*.1) is given to the interface, and on the switch side an IP is given for a management IP (*.2). The switch complains about having the VLAN management IP on the same subnet that it was already given from the DHCP at the router but that's easily fixed by putting VLAN1 on the switch onto a dummy network.

My question is pretty simple, or complicated, I'm not really certain. Is what I'm doing here with the VLANs and interface IP assignments sensible? This seemed most logical to me when I started the VLAN setup from pfSense, now that I'm into the switches I'm not so sure.

Thanks.

I think I probably made a few things unclear in my initial diagram, the intention was that each of the VLANs occupied every port on their own independent switch. I've done an updated and simplified diagram and explanation in a different post that has more to do with the implementation at https://www.experts-exchange.com/questions/28236045/PowerConnect-pfSense-VLAN-configuration.html.

Thanks for the comments so far, I'm at least a little comforted that no one told me I was doing something entirely stupid.
