Mass Effect 2 questions (spoilers)

Okay, so I just finished ME2 and it was freaking awesome! There was no part of it that I didn't enjoy (I even managed to enjoy the planet scanning aspect), and now, as it is with all Bioware games, I am planning a new playthrough. I am going to be either Infiltrator, Adept or Soldier, but I KNOW I am going to be True Renegade since I was True Paragon the first time around. I am tempted to go through the entire ME1 game again with the new class to get all the back story in there, but after playing with all the gameplay improvements, I don't think I can do it. So, here are my questions:1) How do you get everyone through the suicide mission? The first time through I got Grunt, Mordin and Zaaed killed, and I am wondering how to get everyone through alive.2) After playing Vangaurd, I am now looking for a new class to try out. I thought about Infiltrator (I have missed sniping foes), Adept seems a little too close to Vanguard, and Soldier seems like it would take away a huge part of the personality of the game by taking away my biotics and not even replacing them with tech abilities. Which would you say would be the largest and most enjoyable change of class for me?such a fun game, can't wait to go through as Renegade to see how things change!Mass Effect 2 questions (spoilers)
1. Upgrade the Normandy from your team mates and make sure that they're all loyal to you. Once those two are set, you also have to make sure you give the right person the right actions during the last portion of the game.2. No idea, I'm a soldier through and through.Mass Effect 2 questions (spoilers)
yeah I fully upgraded the normandy with the new armor and cannon (I didn't get the medbay because I was paragon and my scars healed by themselves) but I figured the reason I lost people was because I chose the wrong captains for each team... any clue as to who I need to assign to what in order to get everyone through?
ya the ship only needs like 3 of the upgrades i think, that saves jacks, tali, and somone else.use tali or geth in the tubeand use garrus as team 2 leaderi sent grunt back with the surviorsand used jacks to protect me from the swarm, (at the end she gets mad and throws the bubble up the ramp killing eveything, which is a bit badass)and i used garrus again as the distrasion team cause i think who ever you pick has to be able to take hits, ie anyone with armori think at the end i rocked a group with miranda and jack
Use the sticky please :P.
