Hi Jimba,
I have the 9976 and it does indeed come with a wall bracket to mount flush on a wall.
It does not have standard VESA fixings on the TV/bracket though so you will need to buy a universal bracket (such as PF1 from here -
http://www.raw-int.com/products.php) if you want an articulated arm (such as PSA1 on the 'Raw' website) in the future.
And yes, I would suggest getting a professional to put the tv up. It weighs something like 20kg so you'll need some very strong (and the correct type of) fixings.
Cheers,
Pete.
