> 1. When encrypting to a legacy RSA key, I get 3DES, not IDEA, as my cipher choice even though the IDEA plugin is installed.  I have no cipher override in the options file, though at one time I *did* have 3DES there...  Of course, if --pgp2 is used, IDEA *is* used as expected.  Perhaps I should place --pgp2 in my options file? Are there any disadvantages to doing so?

Yes, you are helping IDEA and the idea of protecting ideas to survive ;-)

> 2. Is it normal for an RSA key gen to build a signature-only style key?  Why?  I can add a subkey for encryption, but why would I want to do this?  I know RSA is not the preferred choice for GPG, but I'm curious if this is the intended behavior.

Yes, because RSA is an optional algorithm in OpenPGP and there is only
one default.  If you know what you do it should be easy for you to add
a subkey.
