Router, switch, and VLAN questions

Hello,
I am a new customer and I could use some help understanding some things before I implement. Currently the company owns a Netgear GS324TP POE managed switch and a Linksys WRT3200ACM router.  We just ordered 8 Polycom VVX phones, so there likely won't be more than 10 simultaneous calls, but I expect the company to grow and therefore I should plan for up to 20 simultaneous calls.  I plan on connecting the desktops to the 2nd port on the phones.  Other ports on the switch will connect about 7 printers and scanners.
I am led to believe that I should configure VLANS on the switch, one for tagged voip traffic, one for data traffic (desktops and printers) and one for wifi, plus the default VLAN for management.
I can configure the VLANS on the switch, but I'm not sure if the WRT3200ACM router can deal with VLANS.  Does anyone have a recommendation for a proper router that I can configure the various DHCP interfaces on to accomodate the VLANS?  I'm thinking of the Ubiquiti USG router.  I saw an excellent Youtube video by someone that explained his setup pretty well.   I'm not an expert with any of this and would be happy to pay an experienced network engineer to help me out by phone.  I appreciate any advice you can offer.

Michael, I really don't think VLANs are necessary.  I base that on having several clients, as small as 10 phones at a single location to a school system with 100+ phones at four geographic locations, and none of then have a VLAN. Traffic shaping, QoS, Prioritizing traffic (everybody & every manufacturer has a different name for it) is what I recommend you research and apply.

Thank you for such a quick reply.  So, having the desktops plugged into port 2 of the phone won't affect the quality?  I was under the impression that if I created separate vlans, I could tag the voice traffic on that port and not tag the other traffic, therefore the voice would get priority on that port.  But if you don''t think that will be a problem, that would simplify things for me.   Next question:  The things you recommended, the traffic shaping and QoS, those are done on the router, the switch, or both?
I will research at your links in the meantime.  Thanks again.

There are so many variables that need to be considered in order to provide the best answer.  But the quick answer is this; if you have a single Ethernet connection, back to the network, the phone will be given a unique IP & MAC address and the PC will be given a unique IP & MAC address.  In terms of QoS shaping; only one device and preferably the router/firewall.

Thank you. I will research that.  I'm pretty sure mac addresses can be prioritized on that wrt3200acm router.

One more question that Netgear wasn't able to answer.  The switch has an "auto-voip" feature that can be enabled on each port.  If I have desktops connected tot he phone, and if I turn on auto-voip on that port, what would it do?  Any idea?

Based on my answer above, I'd say this would be moot so I'm going to take a mulligan on this one.
