Given a travel related situation, and given a specific question about the situation, summarize the question into a title

My girlfriend is flying from to Missouri later this month to visit her family. Her sister, in Missouri, wants her to bring her game consoles so they can play games together. She will also be visiting for a month.

How can I safely pack these items with her? She'll be bring two consoles, a couple of games for each, a laptop, tablet, books and clothes. So far, my idea was to pack everything that can't be damaged into a checked bag, bring the consoles in the overhead bag, and her tablet/books in her carry-on. Is this a good strategy to prevent the most probably damage? What sort of accommodations should I make for going through security? I won't be going with her, so I can't go through security with her, or tell her how to get to her gate. The other option we've found is to have it shipped over there, but that involves paying to ship it over, and paying to ship it back.
