Episodes 151-154 include footage from  The Diamond Dust Rebellion , so it's about time you saw that movie. However, the movies are more or less freestanding, and not canonical, so they rarely reveal anything important about the series. If you still wish to follow the chronological order, then  Fade to Black  takes place around episode 200, and  The Hell Verse  around episode 300.
