Mass Effect 2 (2010)

When should I play DLC?
want to import ME2 saves to ME3, but Im worried my save will be broken or somth. Im planning to play DLC (except character ones) AFTER I beat collectors, so I can have Legion as companion without ♥♥♥♥♥♥♥ up final mission.
So my question is, if I start playing DLC after suicide mission, will importing my save to ME3 will be ok? I remember reading something about beating all missions and DLC before final mission, otherwise they wont count when importing save
