Well to answer my own question, I have come up with the following (minor) changes:
- The right-of-RH-pinky column is changed so that it is more like the QWERTY layout: "-_" is next to '0', "\|" is next to 'L', and "/?" is next to 'S'.
- Following the bradheintz suggested LH punctpad changes, I changed/added: '/' on 'U', '?' on 'E', ''' on 'O', '"' on 'A', ';' on 'P', and ':' on '.'
These are the changes I've come up with so far in the week or so of typing slowly with the Dvorak layout. More suggestions are welcome.
