Quality links are essential in SEO, though this will also be measured on trust, spam and authority. Therefore, before you start embarking on your SEO effort you must understand first its process and how could it help your site rank specifically. And of course, choose your competitive keywords you wish to rank.
Your own page rank isn't that important. Many website which have a PR of 1, 2 or even 3 can rank very highly its about the quality of the conent of your web pages and then the number of quality backlinks
You have to mix very well On Page with Off Page, even though Off Page doesn't play such an important role anymore. On page requires actually more attention than ever and that's because Google's Policy changed into a different direction with the latest algorithms. Personal I found this a positive thing because to much spam was around. Now pretty much everyone has to update to live.
You need to be visible enough to Google and get quality backlinks that is healthy and authoritative as well. Just and then, you could start working on the factors such as link building efforts to achieve your desire Pagerank. Furthermore, I would recommend you to focus first on SEO strategy that does matter to search engines ranking, and everything will come next.
By putting rich content in your webpage for which visitors looking for and doing off page SEO techniques such as-
1)Link building(by blog commenting,by forum posting).
5)Web 2.0 submission.
Your question is the first and biggest mistake all beginners make. They are all obsessed with page rank and where they are in the serp's. If you want to succeed in the industry in any kind of way, don't go down that road.
Websites that rank well in search engines do so because of the amount of traffic they get. It's a chicken and egg situation. If you create good content and share it, traffic will come to you. Traffic leads to relevant quality links, which in turn leads to high ranking. NOT the other way around.
You can go out and build fake links and maybe....just maybe you might rank well for a while and you might get some traffic because of it but if the content doesn't stand up on it's own, it wont last.
You need high authority backlinks from do follow sites. Also you should create an article bank or Wiki on your site that includes every known information about your niche or site topic. That will make you look like an authority to Google and they will reward you accordingly.
One of the best ways to gain traffic for your blog is to do the Off-page optimization. Post your blogs to websites with high PR and make sure that the content is completely original and in well-written.
