This time, save in different slots, don't save over older saves. There's a reason my ME2 (and ME, and ME3, when it comes out) playthroughs have about 40 different saves (give or take), stretching from just after Freedom's Progress all the way to having finally gotten all the worthwhile upgrades from the Shadow Broker (and having completed every DLC).
