What do you mean by, "...hard to shift..."? You can't reach the levers from the drops? The lever is difficult to push because it requires a lot of effort? What exactly? I upgraded my '14 from Sora to 105 (5800) and one thing that I did notice is that with two more gears, it takes less effort to switch gears in either direction. But I didn't find it particularly difficult to shift from the drops with the Sora.

IIRC, the minimum that you need to change in order to switch "up" to Tiagra or higher are the right shifter, cassette and chain. You can try to source the individual parts from eBay, just make sure that you get the same series components.
