If we allow custom palettes (which we definitely should if we have a
palette view), then it'd be good to have a drop-down list of the palettes
rather than a spatial view, or we could have both (a drop-down with
left+right arrows at the side).

My thoughts on that in the last mail.
I'd prefer to keep the color previews in a single row.

The color selection is identical to that in MS Office. It's not a
requirement, but it's good for compatibility purposes (e.g. if a user loads
an MS Office document and wants to reuse one of the color variants), so I'd
keep it the way it is.

A vote isn't a reliable way to discover what's best for the user.
A usability study, perhaps based on Inkscape, which includes views for both
sliders and a wheel, would be much more accurate.
Perhaps we should invite Bjorn Balazs to help us with that?

The branding theme should be used for marketing purposes only.
I was originally thinking we could use Tango as well, but some of the
colors look quite bad when they're used in documents, especially the
greens, so I'd rather opt for something we make ourselves, something that
we know looks good on any background and in various use cases (text,
shapes, graphs, tables, ...).
