2:
Lair of the Shadow Broker, especially if your a Liara fan,
Arrival, if you want the story behind why Shepard was arrested and taken back to earth
Kasumi, my favorite, gameplays a little different and you get a new team member
3:
Citadel
Citadel
Citadel
Seriously if you can only afford the one get Citadel, it's the best dlc I've played in ages
I'm actually debating on if I should have Femshep date Liara again or not. 2 and 3 don't introduce any new lesbian love interests do they?
For starters: putowtin named pretty much all the DLC that you should get. Citadel is a MUST for ME3. As well as the Extended Cut (which is free and improves the much reviled ending).
As far as romancing Liara is concerned, if you ask me she's the "canon" girlfriend in for Shepard.
1: She can be romanced by MaleShep or Femshep.
2: She's the only romance option available in all three games
-As a side note to that, however, you need the Shadow Broker DLC in ME2 to continue the relationship if you romanced her in ME1. And even then, you don't get a love scene, but you do re-assert your love for her, steal a couple kisses from her, and have an intimate chat in the captain's quarters of the Normandy in 2. You don't
have to have the Shadow Broker DLC to continue to romance with her, you just have to make sure you don't romance anyone else. During the part where there should be a love scene, you'll see Shepard looking longingly at a picture of Liara. This happens whether or not you get the DLC, but as I said: if you do get it, you get to steal a number of kisses from her.
3: She has a lot of intimate scenes - whether or not you romance her, but they're more meaningful if you do - in ME3 than any other character.
To my knowledge, there are no new lezzy scenes to be seen in ME2. I had thought you could probably get one with Jack but I've never managed to do it.
Back to the "necessary DLC". Arrival is pretty good and worth it. It was the last DLC for ME2 and is essentially a prequel mission for ME3.
Kasumi just gives you another character and a special SMG for your SMG characters to use. It also allows her to pop up in ME3 (assuming she survives ME2's final mission) which gives you access to two War Assets, where-as without her you have to pick one or the other. Same thing goes for Zaaed Massani (spelling), for that matter. Zaaed is actually pretty useful in combat, his Inferno Grenade ability is great and I love his voice actor. But neither of them necessarily add anything to the story. As far as ME2 story DLC is concerned, Shadow Broker (highly recommended) and Arrival (could be skipped because the events are mentioned in ME3 whether you do it or not, but I'd still recommend it) are the only ones you should concern yourself with.
As for ME3, again: Citadel is an absolute MUST! It's got a great sense of humor and you get to have a party with all surviving squadmates from all the games attending. Also: you can have Wrex join your team again for a couple missions which is just awesome by itself.
Leviathan adds a lot of background story for the Reapers. Specifically: you learn exactly where the Reapers came from and why they were created (if Star Child's explanation wasn't enough). I'd recommend it, but really it's not all that critical. It also allows you to unlock the Dominate special ability which lets you mind-control organic enemies for a little while, making them fight for you. It can be pretty handy
Omega was a huge disappointment, and I'd say that one can definitely be skipped. Plagued by graphical glitches during the cutscenes, it doesn't really add much at all to the story. They kinda just did it because "fans wanted to go back to Omega, so we'll make a DLC based around that." It has absolutely nothing to do with the story, the only perks to it are the fact that you actually get to have Aria from ME2 as a squadmate for the duration of the DLC, you get access to a new special ability called Flare which is a massive biotic attack (basically it's like a super-powered version of Warp that causes it's own Biotic Explosion, and makes a bigger one if you use it as the trigger for a biotic combo), and you actually get to see a female turian who joins up with you for most of the DLC. As I said though, it doesn't really add much to the story at all and can easily be skipped unless you're a huge ME fan and just want to experience everything there is to experience with regards to ME.
In short, the Must-Haves are Shadow Broker (ME2) and Citadel (ME3). Arrival (ME2) and Leviathan (ME3) come highly recommended by me, but aren't critical unless you want to have as much of the backstory and lore as you can get for the series.
