If you want to specifically refer to the tangible resources - the actual bundle of logo files, brand guideline documents, images, etc etc, you could say "brand assets".
Most of the other answers also cover the intangible conceptual side of a brand style and image, not just specifically the nuts and bolts, eps files, colour codes and written guidelines.
Here's a real life example: http://mailchimp.com/about/brand-assets/ MailChimp's "Brand Assets" section of their web site, which includes all the practical stuff listed in the question alongside guidelines on how to use it.
You can say "brand resources" if you find the word "assets" too painfully jargony.
People sometimes also talk about 'brand tangibles' (as opposed to 'brand intangibles' like market position and the vaguer end of tone of voice) but things start to get fluffy and philosophical there, and it starts getting mixed up with things like the product, service, etc.
Sometimes people talk about brand packages, brand bundles, visual identity kits etc etc as well - but usually only when someone is marketing themselves as a cheap, cheerful, easy provider of such things.
