Electric wall socket advice for my powerline adapters?

[phillai]

So, I wanna delve into the world of powerline adapters.
I only have a double electric wall socket in the living room (which already is being used up by my two Belkin 8-socket Surge protectors) and I don't want to put the powerline adapter into my surge protector (cause I believe its not good!)

As I am already getting some painting done at home, I thought it would be a good opportunity for me to get an electrician in and change the double electric wall sockets to either...

1. Adding an additional double electric wall socket
2. Changing it totally and get 2 x triple electric wall sockets

The things that I'm gonna power up are...

42" Panny plasma
Boxee Box
Apple TV
Xbox One
Xbox 360
PS3
PS4
Wii
Wii U
Sky HD
HP ProLiant MicroServer N54L

As I am no electrician, is what I am asking for too much?
I mean I won't blow anything up, right?

Which should I go for? Two doubles or two triples?

There's no problem with using pass through power line adapters and plugging a surge protected extension in to it is there? I do....

You don't want to plug the power line adapter into the extension though as it ruins the signal.
