What you have here is indeed a structure called SubjectPublicKeyInfo. It's usually part of an X.509 certificate, but it is often also used separate from a certificate. It's, for instance, the default encoding for RSA public keys in Java and - if I'm not mistaken - OpenSSL. You can view the complete structure here and compare it with the SubjectPublicKeyInfo ...

Both the AES key size and the RSA key size matter, because it's no use adding security beyond the weakest link. Here the weakest link is 2048-bit RSA, which is considered roughly equivalent in security to 100-128-bit symmetric keys (depending on who you ask). So having a password with much more than 100 bits of entropy would be fairly useless. In practice, ...
