I'm certain they'll have some effect, but I'm a little worried about some of them. For example, if you save both the Rachni queen and Wrex, what happens? They're not exactly allies. Do you end up being forced to choose one or the other in ME3? For that matter, Quarians aren't going to be too happy hacking a Reaper control panel with Geth guarding their backs. Overall I think the problem may actually be what happens if you DO go all Paragon. Seems like, at some point, conflicts will inevitably arise, and I don't think 10 races that all hate each other equally are ALL going to get along for the sake of saving OUR home world.

Maybe so though. Shep has done some amazing stuff.
