It should also be noted that saving Wrex and choosing Anders makes you a Paragon in ME2, with renegade actions. Same goes for Paragon's who choose to allow the council die and choose Udina. Mixing comes out differently. Save council but choose Udina and you stay Paragon, unless you are Renegade you will become Paragon as far as the point system goes.

I got this info from ME2's pre gameplay where it reminds you of your choices in ME.
