'The Design of Rijndael', plus errata, is available in Joan Daemen's page [1]. As an addition, 'The Block Cipher Companion' [2] is a more recent, less AES-centric, overview on block ciphers. As for elliptic curves, I'm a fan of Washington's 'Elliptic Curves: Number Theory and Cryptography' [3], which contains a lot of detail while remaining readable. But it might not the best introductory material.
