If you have payed attention to your crew members or are using a guide, then no it is not hard however, if you have not been paying attention, it can be very hard.
No, you do not need to upgrade the medical bay to have a zero casualty last mission in Mass Effect 2. The med bay will just get rid of facial scaring.
Yes, it does, if you don't complete Legion's loyalty mission on Mass Effect 2 he won't survive The Suicide Mission, therefore he won't be in Mass Effect 3 and he is replaced by a AI of Legion.
if its mass effect 1 and I'm assuming your trying to do it with Ashley, then you need to talk to her after every mission and always agree with her with what she says. Also, if you have the option, only us paragon quotes. After a while you and she will start flirting then in a few mission before the last on you will "get it on."
It is our galaxy the Milky Way. If you go to the Local Cluster you can look at Earth and in Mass Effect 1 you have a mission on the moon (Luna).
Yes. Bioware has confirmed Mass Effect 3 will be the last of Commander Shepard's fight for the galaxy. However they have not confirmed that there will be no spin offs of the Mass Effect series. Actually, hints have been given that there might be. It was confirmed to be the last mass effect but then Reach was going to be the last halo.... If you've played the ending for mass effect three, i would be upset if there wasnt a sequel, that is a huge setup....... it could just be DLC missions tho!
If you don't get Jack's loyalty she will die on the final mission.

Not all of them. Maybe one or two of them, but all four games will not fit on a 4 gig hard drive.
No. He (can, if he survives a certain mission) be in your party, but you will not be able to play as him.
If you mean the "800 blocks" on the Citadel, then yes, you will go there as part of a mission.
