I used to believe that (a) PR was important and (b) it was indeed dependent on backlinks. Now I'm not so sure. I have launched a few new sites recently and some of them have PR that I simply cannot justify. Despite having very few links, and poor ones at that, some of them occupy positions in the SERPs that are higher than I would expect, too, given their age and backlink profile.
However, PR doesn't seem to make any difference to how successful my sites are. What is more important, IMO, is the type of backlink rather than the quantity; those from related sites seem to be far more valuable, which is of course what we would expect.
