That is a good question fuadkamel. I would start with 7.2.4 based upon what I have read. Others may have a different recommendation.
Second what Wayne said, you will have a terrific system, especially after you get 100 hours on them.
When you have time to kill BEFORE the system arrives; go to the Community in the menu and select "Member Systems" Then start reading and you will find lots of great tips.
I would start with Sandy's tips, read and read and make notes so when you get your system you just refer to your notes. Also start with the factory rubber feet, so you can move them around until you like what you hear and switch to the metal spikes. Pay attention to those crossover frequencies.
If you can, start with 9 ft spacing between the T-Ones, measured from inside corner to inside corner. Toe those baby in so they face your ideal sitting position. And get them off the back wall at least 15 to 18". Start with that sub woofer adjusted to 12 o'clock. DO NOT set above the 12 o'clock position until after break in and you are tweaking. Also, use those 3 feet in the bottom of the XXL center channel to aim that center of the speaker toward your ears, especially if your speaker is way below the HGTV.
I can't help with the X.X.X configuration, I am running either stereo or 5.1 for movies.
And in my opinion, the T-Ones are efficient but I have heard them driven with a 50 watt amp, SS, and a 150 watt and 250 watt amp. You need the headroom that the larger amps offer. Not sure what the power output is for the receiver you bought.
During break in, be sure to use a movie as well for the explosions rather than CD and FM for the burn in.
Finally, there are lots of good tip;s for set up in this form, "Support" - "Support Forum".
Be sure you document your serial numbers as you unpack the boxes for registration.

T-Ones + XXL SuperCenter and 50's for the rears.
