I'm also in favor of giving more attention to the non-letter keys.
Specifically, I'd really like bigger shift and delete keys, and would LOVE the option of removing some of keys I've already assigned to swype actions like the 123..., key, for instance. I also never use the xt9 key, and would love the option of removing it. (I think the idea of moving some of the keys to the suggestion box is awesome, most of these options are not something you'd type in the middle of a word, and it's a perfect way of freeing up space)
As for myself, the ideal layout would be as follows:
-The first two rows would remain reserved for letters.
-The third row would have only the full-sized delete on the far right.
-The fourth row would have the Shift, comma (semicolon as alternate*), space (with maybe an alterante, perhaps long pressing it could give us the xt9/options?), period (colon as an alternate*) and a large(r) new row/next/done/smiley button.
*(there seems to be room for improvemant here, as, currently, I seem to have a discrete comma button, AND comma is the alternate symbol to period, for some reason

)
I'd like to hear what some of the users think they'd like (I realise MY views are specific) , maybe together we could all make something as close as possible to an ideal layout.
