It sais that we will not accept geirim in the times of mashiach, but they will convert themselves and do mitzvos, and the will panic and stop doing mitzvos in the war of gog umagog. This implies that the war is AFTER mashiach comes. is that true?

Yes, Mashi'ach ben Yosef will lead us in the war against Gog and Magog. Later, Mashi'ach ben David will come and rebuild the Beis ha'Mikdash and rule over Israel.
See Rashi to Yeshayah 24:18, to Daniel 9:26, Radak Yeshayah 4:2.
