Amazon runs three columns. J.Crew an Victoria's Secret run two. Each of these vendors is large and sophisticated - I would assume that there are well thought out and tested reasons that each has the layout that they do.
I wouldn't change the layout you have without pretty compelling evidence that it would be to the positive. Is there any way you can A/B it?
In that first visit you want to establish who you are, what you sell, trust, and obvious action items to act upon. It's the building trust and providing action items which take up the majority of the space.
Trust items include the seals of,
SSL cert issuer
professional business orgs
independent reviewers
CC logos you'll accept
Action items include things like,
site search
spot ads
newsletter signups
categories and product links
calls to action like "Click here to get 20% off"
links from within the copy "Our lovely blue widgets are 100% guaranteed to keep spammers from filling your email box"
So the more columns you have the more room you have to jam it all in.
