All the DLC's are replayable, and DLC item packs %26amp; characters are always available. As to the 3 bigger DLC missions. Both can be played at any time after you acquire the Normandy 2 (the Normandy 1 being the original Normandy from ME1) and can travel freely. Though I would recommend playing the Overlord %26amp; Shadow Broker missions prior to your trip to the Omega 4 relay, ideally also before traveling to derelict Reaper (where you acquire the IFF device and Legion.)

The Arrival can also be played at any time, though in terms of continuity I believe the designers intended for it to be played after you finish Mass Effect 2.

Overlord, The Lair of the Shadow Broker %26amp; The Arrival were designed to be stand alone missions meant to fill the gap between ME2 %26amp; ME3. So when you play them within the game is up to you.Mass effect 2 question for all that have finished it?
After you complete the game (if Shepard survived), you should be able to load the auto save and it would bring you back to the Normandy, allowing you to play the DLC. I completed my first playthrough before the DLC came out and I was able to do this without having to start over.

If Shepard didn't survive, then yes, you'll probably have to start a new game. In my second playthough, I started Overlord after the mission where you find Ashley/Kaidan and the Shadow Broker before I got the Reaper IFF. Again, Arrival wasn't released until after I completed that playthrough, so I played it last.

As far as starting over, you will be able to keep the original playthrough, it's all sorted by the character you made. Switch career in the load menu should get you there.Mass effect 2 question for all that have finished it?
you can play all DLC after the suicide mission if you so choose....i've done it many times....i had a few playthroughs finished before any DLC came out....no issues....
