what grades in 3rd year most important + board scores?

Another thread where people discuss about the frustration of clerkship eval: http://forums.studentdoctor.net/forums/showthread.php?s=&postid=500016#post500016

As I said in that thread, I think it is tough when your dean told you all along that "clinical year grades are more important than your preclinical grades BY FAR, and it is during your core rotation year when you learn to become a REAL DOCTOR and know how to work well within a team (i.e. gunner attitude is not allowed), etc. etc. etc. etc."

Then when you go in, you find out that they (attendings, residents) sometimes don't give a crap about what they write on your evaluation and some of your gunner classmates are doing everything to suck up to the attendings+residents (they don't backstab your or anything but they shamelessly lie and proclaim that they want to go into neurology and surgery and ob-gyn and medicine and psychiatry AND whichever rotation they are on; or sometimes, they just lie about lectures+meetings so they can get 1 more hour of sleep than all the other people).

So in the end, when you apply for residency, how important are these 3rd year clinical grades when they can be so subjective? And which ones are the most important? Medicine? Surgery?

And how important are board scores and research compared to 3rd year required clerkship grades?

Thanks!
