"Lebensraum": http://www.dhm.de/lemo/html/weimar/wegbereite... (German only).
Originally a sort of "historical philosophy" which explained history as a permanent struggle for enough space to live. "Converted" into a political program by right-winged groups in the 1920s, demanding that Germany should expand because it provided insufficient "Lebensraum". Became part of and was mingled with the Nazi-ideology as a justification for the attack on the Soviet Union.
"Kulturkampf": Clash between the new German Empire (1872-) and the Catholic Church in the 1870s about the political influence of the Catholic Church (Prussia, the dominant state in the Empire, was mainly protestant).

"raus raus" - very impolite order to "get out of here"
"fila fila" - I haven't got a clue what this means. If it is not poetic language (dada?), then it is not German. Or does ist mean "Fuehrer, Fuehrer". (???)
Actually, the lyrics of the song do not make any sense to me (I have read them on the internet). Btw, the "Kulturkampf" has nothing to do with "Lebensraum" nor with the Nazi-regime, although the term itself sounds a bit like that.

The lyrics of this song are explained on:
