Am I doing this right.............?

Ok, so I went to a lot of search engines and added my site. That's how I get it on google, etc. Right? Which would give me a PR of like 0 (is that possible) or 1 correct? And to get a higher PR I need to create backlinks? Correct? But now, do I need to add a meta tag or anything to my site? If so, could someone supply me with a code to use?
