Jaxson: Whether you opt for your satellite speakers or in walls etc, the pre wiring will be mostly the same, assuming you're likely to mount either in the same general location. I'd run a few extra cables to allow for a 7.1 install at some stage in the future, ~ just leave enough in the wall cavities to be fished out at a later date if required.

Also think about the sub location, either pulling an all in one pre terminated sub cable, or some RG59 coax you can terminate yourself later. Your sub will need a power outlet nearby too.

All the usuals from there, as in if you're wall mounting a TV then ensure you get in now with some additional bracing to hold the tv mount and allow for an electrical outlet up the wall to power the TV. Give a lot of thought to where your receiver/bluray player/freeview PVR is going to be physically located. You'll want to run cables from the TV location back to this gear, so you'll want a heap of connectivity options between there. Also some ethernet cables if you're looking at connecting data to a TV/PVR/Bluray player etc, either now or in the future.

There are other posts on here about faceplate outlets for this sort of thing. I'm big on one cable between two devices so I'd look at brushed faceplates etc, but you can install terminated face plates if you desire, and run fly leads between the device and the wall. It gets more involved if you're looking at putting everything in a cupboard quite a distance away from the TV etc.

Thanks for those pointers - I think I have almost all of the other stuff under control, just the speaker placement is making my head spin with the options. Definitely have the networking / TV mounting thing all under control.

The wife is now interested in in-wall / in-ceiling speakers because of the look, but it's a bit of a gamble as I'd no doubt end up buying speakers online without being able to listen to them first.

Couple of things to bear in mind - particularly with in-walls across the front.
Ensure there's a wall cavity beneath and central to your display to accomodate the centre don't want to cut into the gib and hit that stud that was very useful to fix the TV bracket to!
Draw up a plan, nothing fancy and again, specifics with regards the actual hardware isn't important, a 6.5" in wall speaker's a 6.5" in wall speaker they'll all be there or thereabouts for the most part.
In ceilings will probably be easier overall, the downside, particularly across the front is, the sound can appear "detached" from the on screen action.
That said, there are numerous models available that have offset and/or pivoting tweeters to enable you to focus the sound towards the listening area.
In ceilings are good for surrounds and again, a pivoting tweeter will enable you to focus the sound away from the listening area to provide a better "ambient"environment.
As Jaxon pointed out, make sure you prewire for the sub with, an adjacent powerpoint.
Once you've run the cables, take accurate measurements from fixed points (side walls, floor etc), allowing for differences once the linings are on etc and take photo's.
As soon as the gib is up, cut the speakers that way, if it's a f*#kup, it's far easier to remedy.

^ Agree. Also, make it very clear to the builders what you want them to do with your cables. I found leaving a note on the cable i.e. 'Bring out in centre of cavity' meant that the builders did the right thing, most of the time.

Pock: ^ Agree. Also, make it very clear to the builders what you want them to do with your cables. I found leaving a note on the cable i.e. 'Bring out in centre of cavity' meant that the builders did the right thing, most of the time.

What I noticed my electrician doing when placing loose cables for lights etc (obviously I did data myself!) before GIBing was that they staple gunned blue strapping* in front of the studs and taped cables to the strapping so that they were positioned perfectly even if not near a stud or dwang. The builders didnt seem to mind about the ~1mm protrusion from face of the studs when putting the GIB on top.

* By blue strapping, I mean this sort of stuff
