zenpage - archive view

I asked this in a previous post, but we moved onto other issues.

On the 'Archive View' page the 'Gallery Archive' is displayed as 1 long column. Is it possible to change this to 2 or 3 columns to reduce the length of the display?

OR

Is it possible to keep the display as 1 column and have the 'Popular Tags' displayed in a second column next to it?

I appreciate that the right-hand sidebar menu may cause problems.
