Welcome to the Q&A Forum

Darren, nopes. You should be good doing this. You are essentially doing a 301 redirect and you are trying to tell that (current) page is the most important / most relevant page and that's the information/directive that Google is seeking from the Webmaster. Just do it.

Both are great options if done right. My suggestion would be: Use your blog, create a parent category attach a description etc... if need be use child categories & attach descriptions. Use tags wherever possible, do not go over board and remain relevant. Post your articles within the appropriate child categories. You could maximize this effort by having people subscribe to your "post series" they opt-in via email and every time there is a new post a message would be sent to the subscribers. This allows you to stay connected and relevant while building leads. IMO the SEO benefits are greater using a blog as blog posts offer 2way communication, & have a greater tendency to drive traffic & can be optimized easier in and tend to (IMO) be indexed quicker. This is a very condensed version of strategy for what you described but as a general rule of thumb anything dynamic that will require 2-way communication or constant updating / new material is best suited for a blog & anything static that is updated rarely etc... is best reserved for pages. A Knowledge Base for your site is a good idea still and can be optimized. But for the sounds of what you are describing a blog post series would make more sense. IMO.
