John,
Damn. I just sold my DJ-X30E so I don't have it in front of me . I had it as a backup radio and used it just for testing. I don't know how qualified I am to offer advice, but I don't think too many people on here own these. So I thought I would throw out some general thoughts.
The software is available in English from the Alinco website . Copy/paste the link below into your browser. Look on the left hand side and scroll down to the "Communication Receiver" section. Click on the "DJ-X30" link. Once you are in that window, the software download link is near the bottom of the page.
On the spacing, I believe it is necessary to change the spacing/steps when you change bands. However, your 8.33kHz frequencies should remain as entered.
