As a true Trek fan, I must nickpick.
The choice of using the name Delta Vega as the ice planet was a very strange one. Why would the writers do this when they should know very well that it's this type of thing that would anger the hard-core Trek fans who live for cannon detail? It is representative of the disconnect these filmmakers have from the Star Trek purest.
In an interview with TrekMovie.com, Orci said, "We moved the planet to suit our purposes. The familiarity of the name seemed more important as an Easter egg, than a new name with no importance."
I think this decision confused fans more then anything. People are asking questions like...
"How did Kirk just happen to be dumped on the remote world Delta Vega (from the episode "Where No man Has Gone Before) located at the edge of the galaxy?"
"And how is it that Spock Prime just happened to be stranded on that very same planet as well"?
"How in the heck can Spock see Vulcan with his naked eye from such a far off distant planet (and in the light of day too)?"
If the writers would have just identified the planet by a generic unused Trek sounding name, and also just added a small bit of dialog (along the lines of "Captain Spock, we are passing the Vulcan systems habitable minor planetoid Bumblefuck, should we deposit Kirk there?", Spock answers "Affirmative!"). That little bit of extra exposition would have worked so much better for me. It would have made a lot more sense to fully and clearly explain to folks that Spock was placed on the closest habitable observation point to witness Vulcan's demise. It should also have been made a bit more clear that this place was going the first planet type object that the Enterprise would pass on the return to Earth, and that is why it was the most logical place to dump Kirk. Identifying this ice world as nothing more then a very small planetoid would have helped suspend the disbelief on the "how the hell did Kirk find Spock Prive on something the size of a huge planet" issue.
Now to defend the filmmakers.
On the issue of the song, First Contact used Steppenwolf's "Magic Carpet Ride" in one of it's most important scenes. Why was that fine with so many fans? Why is it ok for Zefram Cochran to be a fan of Classic Rock, but not for young Kirk? My only problem with that choice of song (and it's not a major one), was that it did not match the era for that car model.
