comment Frequency of letters change by the length of the texts?
You can generate your own frequency tables based on samples of related text. If you're decrypting data that came from Alex Corporation, build your sample from their public documents. If you're decoding a Shakespearean code, build your sample from the Bard's plays.

comment Timing Attack on RSA
You can try an attack, but it's certainly not guaranteed to be successful. There are many possible types of attacks. You also don't have to let him repeatedly attack you, you can simply record which servers your system attempts to send the key requests to. Note that this is not a comment on the legality of attacking someone's server - even a criminal's server.

comment Calculating amount of time for brute forcing ciphertext depending on the size of the key
For a fairly handy reference that yields data close to what you need, see keylength.com . It attempts to quantify security in terms of comparisons of key lengths and algorithms.
