VIM Plugin and other fancies

I need a VIM plugin that limits the length of lines in the text files I write. In case, I exceed the line length, it should automatically wrap it up. It is not pleasing to look at variable line lengths in a text document. Something simple like the word wrap in a windows notepad. May be, its a built in feature in vim already. I'll look it up and update this post.

Also, I don't like this idea of blogging in this text editor like thingy. I wonder, if I can enter this post in a webpage like environment. If not, I will end up spending most of my time on Blogger looking at this again text editor instead of my template.
