Your Bose Triports will work with any device that has an headphone jack. This enables you to connect your speakers to your laptop, so that it outputs the audio to them.
It really depends on the connection types you have on your laptop and projector. If your laptop and projector have HDMI connections then use this for the image and audio. If not, the next best would be DVI for the picture and then whatever audio connections you have (analog stereo mini jack possibly). If you don't have any digital video connections then use the VGA for the image.

There will certainly be a suitable USB connector to link your mobile to your laptop - most companies supply them in the box with the phone anyway.

If it's a new laptop then it will be able to pick up wifi without any additional equipment. Look on your laptop for a switch that can turn on and off wifi capabilities.

Audio out is a shortened form of "Audio Output". In computer terms, it is where sound in your computer is sent out of your computer. For example, the headphone jack on your laptop or computer is an audio output. It lets your computer "output" sound into an external device like a speaker or your headphones.
I would suggest using an audio slitter cable if it's an old set of external speakersor almost any DVD/BlueRay will have multiple audio in on the back of it (like audio in for TV or audio for Aux or Tuner). Then just set the single audio out to your speakers. Also the DVD/BlueRay Player will be best so you can change which device plays the audio using a remote control. (If I understood the question right).
