Agree with Chuck on his comments. Font size is something that we play with alot, and something that my designer and I argue about often. Seems that designers LOVE small fonts

. You`re OK leaving the 10pt fonts in the menu, as they seem to fit the width best at that size. I would rework the top of the content section to feature your products as soon as possible above the fold. You have excellent product pictures. I think the introduction/welcome text is not needed, and just adds to the clutter on the home page. You have a lot going on there.
Once you get consistant traffic, I`m a big fan of a/b testing for a site like yours. See what your traffic and conversions are like for the site as is for a week or two, then change it around for another week or two. Study whether the new layout did better or worse, or if a hybrid of the two would work best.
