Are you comfortable with the amount of drop your current bar has? It doesn't look like you need less drop, but only you can tell how it feels. You defintitely need a more comfortable drop shape, one where the drops are closer to paralel with the ramps behind the hoods. Whether the Ritchey bar is the one that will feel better, no way to tell before you try it. I would definitely not order without trying as many different handlebar shapes as you can get your hands on. You don't even need to fully mount them on your bike, you just need to feel the shape and angle of the drops

Regarding stem reach, 115mm stems are indeed hard to find, but 5mm of reach doesn't really make that much of a difference anyway. If I were you, I would place a ruler or a straight stick across the hoods, pressed against the bump, and measure from the center of the fork steerer to the leading edge of the ruler/stick. Then, once you've found a handlebar that fits you, you can repeat the measurement, compare the two results, and adjust the stem length accordingly.
