Permalink Edits?

Hey Everyone

I am looking to find a great and reliable plugin that will change the permalinks or "url slugs" on everything. I found plug in to do it with Author page but would love to find one that replaced wp-login as well as the word "blog" in the URL for individual posts. Is this what Pretty Link Pro does? I was a little confused and overwhelmed by the description of that plug in on their website.

Any suggestions would be great! Thanks as always

Mike
