Hah, the reason for the cassette + derailleur is that it work out a bit cheaper than a triple crankset and give a similar range, although with the triple you get more choice of ratios.
With the 11-28 cassette, you get a gear inches of 32 to 121.
With a triple chainring (using your original 11-25 cassette), you'll get a gear inches of 32 to 121 (using the Shimano Tiagra 30-39-50 cassette as a reference).
I think the Shimano Sora shifter work with double and triple, will double check that at work today, however what about bar-end shifter? you can have the option of indexed and friction at the same time, a great option if the indexed is out of tune, simply switch it in friction mode solved this.
I know the Dura Ace one does, but not sure if the Ultegra do as well.
