Stats in green I believe are an increase over what you have, stats in red are worse in that stat I believe. As far as gear goes, I have had "gear become uncomfortable" when I switched from a lvl 12 to a lvl 1. So I would guess reduced effectiveness and/or accelerated durability wear, which is expensive to repair on higher level items.
