Anecdotally, it seems the higher the PR is the more often your pages get crawled by G, so that's a plus.
At any rate, with a PR5 you're doing well.
However, even if PR doesn't directly help your ranking much, it is still an indicator of things that directly help your ranking a great deal. To get PR you need inbound links, and inbound links make a difference (particularly if the have the right anchor text).
High PR, even it if isn't worth chasing in itself, suggests that you're doing some of the right things to rank well.
The toolbar, which shows an out of date rounded figure for PageRank (internally to google an important factor in crawling and ranking), can be safely uninstalled. It has no place, or value, in SEO/SEM.
Get down to the business of getting good SERPS rankings. That's the only thing that has "value".

Say you have 2 pages, exactly the same, with text about "widgets."
All other things being equal, the page with the higher Pagerank score will rank higher in the SERP's.
The way I understand it is that pagerank is generally determined by quantity and quality of inbound links.
There are many factors that affect how your page will rank. Pagerank is just one of those.
A lot of people argue that PR is no longer a big factor in where a page ranks. The main evidence for this is that pages with very little PR can outrank pages with a lot of PR, even when both are relevant to the search term.
When you find this situation do you check the low pr/higher ranking site for spam? If so, report them in Google's spam report.
