I'm would vote #2 (2-column landscape+vertical scrolling). I think the common user will look for the two pages in landscape mode. That's the first thing I noticed missing.
You are very wise to release smaller updates. I get extremely annoyed when there is a massive update, sometimes it makes me feel like the developer didn't thoroughly check their app before release.
Either way, I appreciate the chance the use the app.
