424 Crawl Notices Found - Most of these notices are 301 redirects for our blog. Are notices something that would keep me from ranking well for my keywords?

[classa]

212 are rel canonical and 176 are 301 permanent re-direct. An example of the re-direct is a change I made to the /trackback 302 status on my blog like;

Are these Crawl Notices something that I should spend resources on, or should I focus more on my errors and warnings?

Crawl notices are just that; notices. You should be aware of them but I haven't seen any notices in my campaigns that would be something that needs to be fixed. I would focus more on errors and then warnings, in that order. Those are the items that can hurt you most when trying to increase your site(s) rank. Hope this helps!
