Nope, PR is simply a number and is based on the number and "weight" of the links pointing to the page. It has nothing to do with keywords.

Yes, it's a number kept internally by Google. Unlike the toolbar PR, the internal "real" PR is a fractional number between zero and one. It's determined on a page-by-page basis. Sometimes people talk about their site having a certain PR, but there's no such thing as "sitewide PR." Usually when somebody says that, they're actually talking about the toolbar PR of their site's home (default) page.
Because it's part of their ranking algorithm, they don't reveal it anywhere outside of Google. There's no way for any of us mere mortals to know what that number is. If there were, it would be way too easy for unscrupulous people to "game" the system.
Frankly, the very fact they let us see the Toolbar PR is the biggest indicator of how worthless that number is. If it were used for anything significant in their algorithm, they'd never display it in public.

Backlinks are links from other pages
that point to your page. Technically, they can be located on other pages on your own domain, or on some other domain, but most times people use the term to mean links from pages on some other domain.
A page's PR doesn't just depend on the number
of links pointing to it. PR is also a measure of the "weight" of the links pointing to the page. In other words, generally speaking, a link on a page that has higher PR passes along more weight than a link on a page that has lower PR.
Of course, it's a little more complicated than that.
Each page has a certain amount of PR in total it can confer on other pages. The more outbound links on that page, the less each individual link is "worth."
So a link from a page, when that's the only link on the page, is probably worth more than a link from another page that has the same PR, when there are dozens or hundreds of other links on the second page.
Of course, in real life there are a number of other factors that come into play which can make it even more complicated, including how the links are coded (such as whether some (or all) of the links on the page pointing to you have the "nofollow" attribute appended to them) and whether Google is allowing the page to pass its full potential link authority or if the page is operating under some kind of penalty, among other things.
The thing is, Google plays PR (the "real" PR, at least) very close to the chest.
It's impossible to say "how many links" you need to achieve any given PR number for a page, because we don't know what the real PR number is for the pages that link to you, we have no way of measuring how much PR each link passes along exactly, and we don't know what the real PR number is for your page (so we have no way of knowing when -- or if -- we've achieved the goal).
Fortunately, PR is just one aspect of the ranking algorithm, and it isn't necessary to know the real PR number of a page, or the amount of PR passed along by the links pointing to the page, in order to successfully optimize that page.
