Where can I find something like description, specs, details etc for MacBook Air 11's motherboard (logic board)? I need full information about all parts of motherboard. I tried to google it, but it didn't help. Any ideas?

I am not aware of any manual that contains this information but here is a breakdown, since this is one of the big reasons I got a MacBook originally.
The mini display port allows you to add an additional monitor to your MacBook. Support for this is built into the OS directly so you simply connect your external monitor using the correct MD/VGA or MD/HDMI or MD/DVI connector if the monitor does not have a display port and then you can configure how the displays work. This is done under the Displays option in System Preferences.
From the screen shot below you can see I am running a second monitor on my MacBook Pro at the moment and I have set the second monitor to be to the left of the main one by simply dragging it's rectangle to where I want it.
You can also move the menu to a different screen by grabbing the white strip on the primary screen and dragging it to another screen you want it on.
Each display can have it's own separate resolution and even separate backgrounds. The relevant preference panes will automatically show a dialogue on each screen if it supports multiple displays, for example the Desktop & Screensaver will show on both screens.
You can also choose whether you want to mirror the display or use it as a second screen. In mirror mode it simply mirrors everything on your main display.
Yes, you can do this, provided your system will successfully boot from an external volume still. Failing logic boards don't always do this. Each time you boot you will need to hold the Option key down.
The speed will be noticeably slower, maybe even painfully so. The internal drive connects at 3000Mb/s. A USB 2.0 stick will connect at a peak speed of 480Mb/s with regular throughput being much slower.
The largest USB stick you're likely to find is 32GB or 64GB. A 320GB+ drive will be a full portable external hard drive, much bigger than a simple USB stick. And bear in mind above all else that this is not a long-term solution. Your logic board will only get worse over time, not better.

iFixit has nice teardowns, with chip references. No specs about the chips themselves though.
