Like I said, an extra layer of bar tape on the left side only will give some extra padding. Also, a shorter stem will take a little more stress off your arms, since you won't be stretched out as much.
Since the Ridley website is "so helpful", I can only guess at the stem length; the picture gives me the impression that it's 120mm. Price Point has a 110mm stem for $13+shipping. (I'm also guessing the bar/stem is 31.8 -- check your bar, does it have a BIG bulge where it fits in the stem?)
I don't know what kind of gloves you have, but Specialized makes (or used to, I tend to ignore them for my own purposes) a Body Geometry glove that had special padding ARRANGEMENT in the glove to max out the comfort and minimize the pressure.
