It's also related to the nature of the links to the individual page; that's not exactly the same as the page's PR, but it's pretty hard to separate the two things.
You can guess at the quality/volume of IBLs into a domain by the number of pages in the main index. If you have thousands of pages indexed, that usually implies a TBPR 5+ (from what I've seen) and results in deeper crawls.
The speed of crawl IMO depends also on how often new pages are added to your site. If you're working with an authority site, I think adding new urls to Google Sitemaps is the quickest way to get them crawled. If your site is new with very few IBLs though, Sitemaps will probably not help.

Helps as 1 of several factors in SERP rankings
Helps determine which pages are supplemental index an which are standard index, as long as a page has enough PR to avoid supplemental status, i have difficulty seeing why PR an crawl rate should be related.
E.g. Say a research fellow at standford, or cambridge or mit or,,,,,
posts a prize winning and definitive paper on the net,
That page might get update only 1 time in 10 years, but it would probably be TBPR/PR 9 or 10
So why would a SE crawl that more than 1 time per month
On the otherhand
a blog by say a stocks an securities expert, updated 10 times a day, TBPR/PR 4. Should the SE not therefore crawl this blog 4 times a day,,,
