LAN/WAN same switch? How to for VLAN n00b?

[expohl]

So say I have a 12port wisp switch and on that site my backhaul is from a airfiber and my access point is a rocket, what is the best/easiest way to setup a vlan to accomplish this?

There is two ways I think,

Method 1 would use 4 total ports on the wisp switch, 1 for the AF POE out and another to the router WAN, another for the rocket POE and a forth to the lan side of the router, advantage simple setup? Full throughput, disadvantage you take 4 ports.

Method 2 would use 3 total ports on the wisp switch, 1 for AF, 1 for rocket and 1 trunk port to the router, the trunk port goes between the switch and router with 2 vlans, VLAN 100 for example would be wan to the AF and VLAN 200 would be lan to the rocket, advantage would be less utilized ports disadvantage would be sharing throughput on the single port (which won't be a problem in my scenario)

Could someone give me a few hints on which one is better and maybe a hint so I can try to configure it myself?

Thanks much,
