There are enterprise level systems that claim to be helpful, and, in terms of exploring existing competitive backlinks and anchor text, they probably automate some tasks that are more work to do manually. But you will be thinking in the same box that everybody else is in (if you are thinking at all), and that can be limiting.
For starters, anyway, I'd recommend studying the references in this current thread, even before considering outside tools and services, to get an idea of what good link building involves....
Have you read any Good Link Development Blogs/Articles?
