The typical way to do this is with send hooks or folder hooks.  Use
my_hdr in one of those hooks to set the From: line.

Same answer as above, but instead set pgp_sign_as.  If need be you can
use a hook to set your pgp_encrypt_only_command and/or
pgp_encrypt_sign_command (and set the ID to use in those, or use a
different gnupg options file, etc.).
