Welcome to the Q&A Forum

Our agency uses Buzzstream and I highly, highly recommend it. Definitely worth checking out.

It's kind of hard to understand this situation but Ill take a crack. Dont worry about Panda as long as you aren't one of those that squeeze the same grammatically wrong keyword phrases, over and over and over. Optimize the new content for the weaker words -> include those target key phrases -> internally link to the main page you want those to be optimized.
