Problem is still unsolved.

But if nobody has any thoughts about how to fix that - here is a possible solutions to help those, who can see this topic (guys from russian linux forums helped me).

You can type in your console:

syndaemon -t -i 2 -d 

This means, that your touchpad will be disabled until 2 seconds after your typing will passed.

But there is a way to fix problems with turning offon your touchpad and with enabling LED works properly... But this way is complicated.
You must download this patches http://abhinandh.com/post/4336662463/getting-the-double-tap-on-the-led-to-disable-touchpad
One patch is for kernel and one for xorg server. Also you have to change function parameters.
