Telia Bredband, IPTV VLAN

(Sorry for writing in English, I read Swedish but can't write it

I've read a lot here but can't seem to find the answer to my question, which probably means I am way off, here goes:

I have öppenfiber and gone with Telia for internet (100/10), iptv and telefoni. Öppenfiber fitted an Inteno XG6746 broadband switch (http://www.inteno.se/store/tabid/141/categoryid/130/productid...) - this converts the VLAN to 3 ports, Internet, IPTV and Telefoni.

LAN1 I plug into my Asus RT-N66U, LAN2 is for the Ruckus which transmits to the living room where the IPTV box is. I skipped the telephone for now as it's yet another box required off the Inteno Switch.

I can't run rj45 cables to where the TV is in the house (TV, PS3, AppleTV, Motorola IPTV box). But I'd like an alternative setup (to try):

Question: I've read that the latest firmware for RT-N66U supports Telia VLAN splitting, so what I'd like to do is lose the Inteno broadband switch and plug the Asus directly to the fibre via WAN port, then send the Internet data + IPTV VLAN data tags over wireless (tagged), OR Internet data + IPTV out of a LAN port on the N66U router to a Powerline Homeplug? In the living room, I'd like to pickup the Internet Data + IPTV VLAN via wireless or powerline and convert it out to appropriate ports, maybe use the Netgeat GS105e or Wireless ? This way I lose the Ruckus, and get a switch behind the TV for IPTV and a few free ports for Internet, Don't know if this is called "Trunk" or simply forwarding the data VLAN from Telia "as is" and splitting it where I want it split, rather than where the Fibre comes into the house where the Inteno XG6746 is located? Another option might be to transmit the IPTV via a Guest Network?

The wifi signal is good, see 70 - 140mbits where tv is from basestation RT-N66U.

Is it possible?

Any thoughts would be most appreciated!
