I agree with you on the duplicate content issue. Duplicate content can be an issue for sites in general, but it's permanent duplicate content that causes problems. When you post often enough, the home page posts cycle often enough that you don't need to worry about it there.

I think limiting the number of posts you display on your home page is a good idea. It'll help your blog load faster, and cycle posts off the front page quicker. Make sure you have a "recent posts" list in the sidebar, so people can get to recent posts that have scrolled off.

You've got a good permalink structure, too, so you should be in pretty good shape for SEO, if your theme is optimized (or you're running something like the All-in-One SEO plugin).
