Hello,

If the article is sponsored by you and is all about you, I would request no-follow. If it was not sponsored by you (but still by someone) and there is only a brief mention of you and a link I would keep that as a follow. At the bottom of this article from woorank it explains similar circumstances.

Thanks,

That should not be an issue. Just incase I would put - Updated - in front of your title. and a blurb about what it's updated with in the beginning of your description.

They're only free if you went to Mozcon. Discounted with subscription. I believe last year they were $500 standard price for the bundle.

(Which is still a great deal for the knowledge!)

Pete,

You shouldn't have more than 200 links on one page. I don't see why you would need  so many duplicate links, a few yes, but 50%?
