Yes. The Nintendo DS has the same headphone port as the PSP, so the headsets can be used on both. It is probably recommended, though, that you use the PSP headsets for the PSP only, considering that it was designed for the PSP. In practice, you may use them for both. Source: I own a PSP and a DS :)
Yes you can, but it is kind of tricky. First, buy a USB to 3.5mm adapter. Next, buy two 3.5mm "Y" adapters (one for the mic and one for the audio). Last, buy two 3.5mm wired headsets and connect them all together. This will allow two players to chat with other on-line players at the same time. This does not work for game sounds or audio from other media like movies, only for chat. Unfortunately, this does not work for USB headsets or Bluetooth headsets.
Call of Duty 3 first of all needs to have the ability for online multiplayer gaming, (which it does). It also has to be able to handle multiple people on the same xbox 360 console and at the same time being able to play online multiplayer. Halo 2 for example can have 4 people playing on the same xbox console and at the same time connecting to other xbox consoles for online multiplayer gaming. If the game can do this, you must also have 2 different xbox live accounts. You can not use a guest off of another account as an xbox live account because the guests do not have the ability to talk through a mic, even if you have 2 mics. If you have 2 xbox live accounts, then the two of you on the same console can talk to other players on xbox live as long as you both have separate accounts, controllers, and mics.
A sim that is not in a romantic relationship with any other, and does not live in the same house/household as any other.

The Same people will be in it but I've heard that Ramm is comming back
Provided (a) they have the same connector (usually 3.5mm plug) - AND - are the same impedance (8 ohm) they should work.
No. Your family are the people you're related to. The household is the house that you live in.
no
yes you just need a ethernet cable hook up to the back of the two xbox 360 consoles.
yes you can
Yes it is possible. IRS considers a household not to be limited to residents in a structures ("by that logic there would only be one head of household for an apartment complex 'if it were one address'"), instead they choose to understand that more than one household can reside in the same building with the same address at the same time. Beware there are rules for establishing more than one household at the same address.
it means they live in the same house
I have discovered that the best Bluetooth headsets is of the same brand. For example the Nokia phones work best with Nokia Bluetooth headsets. Usually this is how it works because accessories sometimes don't work as well if they are from another brand.
Stereo headsets would primarily be used for listening to music. With a stereo headset there would be two different sounds of the same track coming in through both earpieces.
The PS3 can operate a combined total of 7 headsets/controllers/other accessories and the Game determines how many can operate at the same time.
