Forum:PS3 ME2 Downloadable version questions

Hello there, I'm thinking of buying the downloadable version of the game for my PS3, but I have some questions first:

1 ) Will my game come with ME: Genenis (that's the name of the ME1 Comic, right...?) included in the Main Game Download or will I have to download it separatelly? If it comes separate, how big is it? How do I redeem my ME: Genesis? Really want to know if I have to download more or not, as my internet is very slow. I've already downloaded the Main Game (got the Trial, for beeing PS+), so I don't have to download that, but the DLC...

2) Same question to all other DLC.

3) Can I gameshare the game? For those who don't know the term, it means having a friend access my account, donwload the game to his PS3 and playing with his account. I suppose you can, otherwise you wouldn't be able to play offline, but who knows.

4) How does the downloadable version run, compared to the disk one?

Guess that's all. Thanks!
