You have managed to pick one of the most analyzed themes for both of these novels, so there is a huge amount of literature out there on these books. The key to writing a good literary analysis is not to take the ideas of other articles to make them your own, but to come up with your own unique point in the analysis. It really helps if you apply one of the critical lenses of literary theory to the books.
The Perdue Owl is the greatest resource that you will find for learning the critical lenses. Go to that link and then read a little about the lenses on the left side of the page. The theories that I think would best fit your topic would be marxist or even feminism, but trying reader-response would be a very very interesting choice. The best thing you can do is learn the lens, and then read through the novels while it is still fresh in your mind. That is how you will pick out the little details in the writing that would have otherwise been completely skipped over.
As far as getting some articles: I did a quick search on Ebsco using their megafile and the MLA directories and found a large amount of them that are on your topic. If you don't have access to Ebsco (ask your school librarian) then you can PM me your email address and I will send you the PDFs of a few. You can also use Google Scholar to find some nice articles. Remember though, you are the one that is supplying the ideas about the novels, so it may be a good idea to find some articles that are not related to the books at all. Try searching for something along the lines of "Violence in human nature" and read up on those articles.
Let me know if you need any more help, I am a graduating English major so I am already in scholar mode. I have done dozens of these types of analyses in the past.

I actually do the audiobooks since they have full cast for each character, they are pretty incredible. I only have ender and shadow series in book form. Amazon probably has a pack
Here the first formic war https://www.amazon.com/Formic-Wars-Trilogy-Boxed-Set/dp/0765390701
I'd wait until the queens comes out if you want a boxset of that. Probably be a while since the hive just came out in June
From the original source at Amazon:
Release Date: October 10, 2017
Synopsis: Children of the Fleet is a new angle on Card’s bestselling series, telling the story of the Fleet in space, parallel to the story on Earth told in the Ender’s Shadow series.
Ender Wiggin won the Third Formic war, ending the alien threat to Earth. Afterwards, all the terraformed Formic worlds were open to settlement by humans, and the International Fleet became the arm of the Ministry of Colonization, run by Hirum Graff. MinCol now runs Fleet School on the old Battle School station, and still recruits very smart kids to train as leaders of colony ships, and colonies.
Dabeet Ochoa is a very smart kid. Top of his class in every school. But he doesn’t think he has a chance at Fleet School, because he has no connections to the Fleet. That he knows of. At least until the day that Colonel Graff arrives at his school for an interview.
It was called the "enhanced" edition. I found out reading the comments (you can see them here). It has pictures in every chapter, two added vignettes and it's like a third of the size of the unabridged version. The original version has something like 300 pages, the "enhanced" is more like 100.
I believe this only happened with the ebook version of the book.
edit: When I found out I had the abridged version, I went out to hunt the original and read that one too.
It's a collection of essays that talk about stuff related to Ender's Game and its impact. I haven't read it in a while but it's decent.
Here's the link to the Amazon page for it: https://www.amazon.com/dp/1937856216/ref=cm_sw_r_cp_awd_rtpywbRE4R4B8
