Hi Checkin, First off welcome to the forum glad to have you with us.
Now onto your question.
When ever I get PLR of any type I always rewrite it to make it my own content. I think of PLR articles as a starting point for me when writting rather than starting with a blank screen, they help to give me inspiration to cover the niche topic at hand, and put my own spin on it.
Keep in mind, you don't always have to rewrite word for word, you can mix the paragraphs, and sentences around which might actually take less time than rewritting the whole entire article. Using them on WEB 2.0 properties with a link back to your money sites can also prove to be benefical.
I would also very much agree with what techtamers pointed out about spreading posting this content out for several weeks, you could always put all the content onto the blog and just schedule the posts to be drip feed.
Hope my answer helps to give you more ideas on ways to use this content properly
