You're right, what you do in undergrad is most important. However, being at a top university makes it much easier to move mountains due to the resources at your fingertips. Top researchers, highly competent peers, eminent visiting professors, and international conferences are invaluable resources. Furthermore, the networks such universities have should not be overlooked. While the situation that Kainzero described does happen, it is definitely an uphill struggle. Just go to the "current graduate students" page of any department in a top program, and you'll see that most students did their undergrad at prestigious schools. Anyway, I should mention that the admissions process I described is from my experience in philosophy. From what I've heard, science admissions are more merit-based and egalitarian (i.e. who wrote your recommendations or the prestige of your alma mater matter little, and the quality of your undergrad research takes precedence).
Personally, I think liberal arts colleges provide the best undergrad education. I regret taking courses in giant lecture halls...
