more people link to the information pages than to the ecommerce pages

That is a good reason for keeping the information pages, IMHO. You're getting link juice into the site, now think carefully about how you're spreading it around.

MIGHT get more people to link directly to the ecommerce pages, and hopefully that will help them rank better

That answers my question about what your goal would be for making changes.

While their are links in the category tree BETWEEN the ecommerce and general info sections, I only include a few.

"Only a few"? IMHO that would be the place to start. Don't move content around, but do look for ways to beef up your internal link structure.

have a HIGH cart abandonment rate

Solving that puzzle should be one of your highest priorities. Finding ways to improve your conversion percentages would multiply the value of everything else you do.
