What an evil PS1 you have! What mean those '[0]' and '[$]' in second
line?

The last command's exit code and \$, I guess?

p. s. I have PS1 like this too. But it's for logins with no
$DISPLAY.

FWIW, I'm using a simpler prompt:

PS1='${debian_chroot:+($debian_chroot) }[\u@\h] \W\$ '

Or, should I need timestamps:

PS1='${debian_chroot:+($debian_chroot) }[\u@\h] $(printf x%08x "$(date +%s)") \W\$ '

\W is quite apt for me, given that I may occasionally have to
visit something like /home/public/users/ivan/download/svn-sync/,
or /home/private/users/ivan/private/slides/debian-apt-2012/.

Not the exit code but the number of the tty. In an X11 terminal
session, it's only a number, because those are pseudo-terminal slaves.
In character mode sessions, it prints e.g. "tty1".

That's why I have the $PS1 split out over two lines. That way, I can
always see the full path without that it consumes screen space I could
use for typing commands. :-)

I also have a newline ("\") at the beginning of the $PS1, so that
there's always a blank line between the output of the last command and
the prompt, which makes it easier for me to read.

^^^^^

That should read "\n", of course. ;-)
