ESC[J clears the screen (probably means ESC[0J  clears from cursor until end of screen)
ESC[K clears the current line (probably means ESC[0K  clears from cursor to end of line)

and finally - http://www.xfree86.org/current/ctlseqs.html#Bracketed%20Paste%20Mode

When bracketed paste mode is set, pasted text is bracketed with control
sequences so that the program can differentiate pasted text from typed-in
text. When bracketed paste mode is set, the program will receive: ESC
[ 200 ~, followed by the pasted text, followed by ESC [ 201 ~.

CSI ? P m h   DEC Private Mode Set (DECSET)
P s = 2 0 0 4 → Set bracketed paste mode. (same page)

so \e[?2004h is setting the bracketed paste mode (probably zsh handles this)
