Hi Masterpiece

yep audio is all taken care of as is key AV to TV unit.  The Projector is the afterthought and its been a bit of a mess keeping ahead of the gibbing. I think I am at a place where I am reasonably happy just got to compromise on a few tiny things.

in the first instance the projector will be table mounted in front of us the throw distance is around 3.5m in this case. The inwall cabling has been all for the TV position.

I did run a second HDMI from the AV cabinet to the TV position and left a tail on the end which I can extend to the projector position and simply run an extension cord to the PJ when in use. Messy but acceptable.

In ceiling I have run dual CAT5/6 + power with the CAT cables running back to the AV rack, so could look at using video/HDMI over Cat5 with baluns. im looking at the HDMI extenders on offer but also looking in to the BenQ wireless HDMI as an option. 

I do like the idea of the wireless option.

As for the remainder of the set up I have in ceiling rear speaker array and also in wall cabling for fronts, centre and sub. The home is wired for CAT5/6 throughout as well.

will post some photos once all done. 

but like I said im on catch up with the projector and learning fast !

From my own experience, whatever your configuration looks like (and however much you spend) you will initially be really impressed...
...And then you start thinking about what you can improve ;)

As I'm in a rental my living room screen is just the free 100" screen that came with the projector, mounted to a couple of 2x3's that sit on top of our shelves (with two 15lb weight discs as anchors).

Have you re-looked at the screen size from a throw of 3.5m?  If you're still looking at the w1070, the calculator I use gives a screen size of 105"-137" at 3.5m. I think you mentioned a 92" screen...

Personally, I had my projector table mounted for all of about a day before I got fed up with it being there (it now sits above and behind our head on top of a media shelving unit).

I agree with K1wi regarding screen size, I suspect you need a 110" screen.

The projector central calculators are extremely good guidance for working out your basic throws.
Projectors are always at their best when no zoom is used, however few have the opportunity to align things that perfectly, hence variable alignment, left right, up down lens shifting(always better than keystone), then there is zoom. The zoom allows the flexibility of range, however there is a limit to all projectors, some have better throws than others, but this usually comes at a cost.

For your current projector choice the calculator says to me a 110"(2.8m diagonal = 2.44m horizontal) screen for 3.5m throw.

If your screen size is 92" and you cant change it, the throw range is 2.8m~3m, if this is a problem for seating you might be left with roof mounting.

The next potential issue is field of view for optimal viewing. The general SMPTE rule of thumb is about 30~35 degrees field of view for 1920*1080 material. Although many find closer to 40 degrees better immersion, where THX guidelines are closer to the later wider FOV.
If your seating is 4m, the 92" is about 27 degrees, a 110" screen at 4m seating is about 39 degrees.

For me the 110" size is more optimal to your projector placement and FOV.

The issue though is with your projector choice, it is some what limited for zoom throw to place it else where than the coffee table or the roof above. If you later wished to place it behind on a shelf at say 5m throw you might need a 150" screen. Other projectors have far more flexible throw ratios. I'd maybe re think the choice for a similar priced projector with more flexible zoom and throw.

I say this because ultimately the coffee table setup has a shelf life(pun)
