I read that Bluetooth on several headphones send the sound with a small delay. This is not a problem when you listen to music or talking with a friend but it is a problem when watching a movie or playing a game.
Could you confirm this delay? Is this delay a problem of Bluetooth in general or only old version of Bluetooth and has been fixed with 3.0 or 4.0 version or is only related to specific brand or i don't know?

"What features would distinguish a gaming audio system from the regular one?"
In my experience, there aren't any such features. I have a music studio, lots of audiophile equipment and lots of gaming gadgets. I sometimes use them interchangeably.
'Gaming' gear is usually targeted at people's perceptions or desires rather than their requirements. If there was one major difference, buying audiophile gear offers a large advantage: They're aimed at an audience who know how to critique their products. Games accessories are aimed at the 'gadget' market - and as such as more likely to be over-priced, flimsy and inferior to an equivalent developed for the audio industry.
Steelsound headphones, for example, can offer excellent sound quality but they can't take any sort of a beating (or moisture) and for the price you'd expect that. An equivalent set of Sony headphones is superior. It's not that the Sony headphones bring any special features to the table, it's the economics of a utility versus a toy.
5.1/7.1/9.1/45.1 speaker setups are intended for home theatre. They are not relevant for video gaming and headphones will serve you just fine. Pro gamers use headphones - there's no justification.
If you are going to buy a decent set of headphones you need to upgrade your sound card to get the benefit of them. I highly recommend little USB stick sound cards, such as those from Steelsound. They're convenient as hell.
Now I haven't really described what definition of 'better' I'm using. Better is fidelity. If you're looking to be competitive, you need to be able to pick out small cues and individual sounds from the mix. That tiny little click underneath all the explosions? That's your opponent reloading!
It's also very important the sound isn't too tinny or thick - huge liabilities when you're trying to concentrate. This comes naturally from getting good equipment with a wide natural dynamic range.
If you're interested in speakers specifically, you can do a lot worse than buying short-range studio reference monitors such as these: http://www.camdensounds.co.uk/monitors/edirol-ma-7a-bk-analogue-stereo-micro-studio-monitors.html They are designed for the studio, they won't break the bank (in comparison to equivalent home theatre/gaming kit) and they sound just sublime - but they're only useful if you're sat in just the right place in front of the screen, conveniently exactly where a gamer sits!
On your PS3 Go to Accessory Settings -> Audio Device Settings. You'll find options for microphone volume there. Try adjusting it to the highest level. Also make sure the Input device is set to Wireless Headset (and not, for example, the USB camera). Make sure you confirm your settings by choosing OK, not by exiting pressing O.
Also, I recommend doing the HQ sync for the headset, to do so, plug a USB cable directly into the headset (not into the headset dock). When you'll trun on or off the headset or adjust the volume, you should see the HQ indicator in the top right corner, it looks like this:
For everything else, I suggest you read the manual, available here or contact Sony's support.

Searching around, they should be fine if you get some specific things. Mainly, it means getting aptx codec, preferably a headset with the latest bluetooth version (4.2 right now if I'm not mistaken) or that provide low latency and a adapter/dongle that has low latency (< 32 ms).
