To answer a few of your questions....

I noticed all the speculation about whether Lelouch was alive in the second season and Marianne's maiden name.

First off, there is no actual official evidence that Lamperouge is Marianne's maiden name. Someone speculated about it and thus posted it on Wikipedia entry like Stephen Colbert's entry on African Forest Elephants. You shouldn't regard this as fact.
(Celiss from Gamefaqs confirmed this)

So yes, he is alive obviously, but why do his eyes look perfectly normal? Speculate :D

EDIT: Someone uploaded the trailer for the second season on Youtube from Nicovideo.

Am I extrapolating stuff, or did we just get a never-mentioned new sibling outta nowhere?

[lulu-quality.livejournal.com]

Eh, well Lelouch has a lot of siblings (over twenty!) so it would make sense some haven't been mentioned.

[ashura-sama.livejournal.com]

Twenty out of which only one uses the name "Lamperouge".

Which Rollo also seems to.

Rollo can officially except not be Lulu's stalker then. Case closed :D
