SF300-24P 24-Port and Cisco WAP561 VLANs

I have one Cisco SF300-24P 24-Port and three Cisco WAP561.  I created a guest wireless network on all the WAP561 on VLAN2.  I created VLAN 2 on switch and all ports on the switch are set to trunk.  My understanding is if port is on trunk mode if will flow traffic to all VLANs but Guest wifi is not working.  When I connect to it I'm not getting a IP address- do I have to create a DHCP pool for Vlan 2?  

Thanks

That depends on how you want to do it, but I'd guess yes in this scenario.  What router do you have?  If it only has one interface you'd have to do it with a trunk, but if it has more than one (other than the WAN port) you may be able to use a specific interface for each VLAN.

Yes you do.  Clients need to get an IP address in order to pass traffic.

Will IP helper be the best method to do this?  Also having a hard time with tagging/untagging.  On cisco switch, the port WAP is connected to needs to be untagged or tagged (trunk)?

It depends on where your DHCP server is.

If you have a DHCP server with an interface on each subnet/VLAN you don't need helpers as the DHCP request will be seen by the server without routing being required.

The switchport where the AP connects should be a trunk as you're passing traffic on more than one VLAN.

Thanks! Also the switch port from switch to router should be a trunk?  Router is my DHCP server.

I have a SonicWall.  Created a sub interface VLAN and it works!!  Thanks for your help.
