I would suggest staying away from Sora if possible. Tiagra and 105 are noticably better and nicer to use. Go for those components or higher.
The 2013 Sora group actually ditches the thumb trigger and goes for the shift paddles like the rest of the Shimano line. It's still 9 speed, though, while Tiagra/105/Ultegra are 10.

Serious question- Do you notice a difference in shifting going from the stock 105 pulleys to Ultegra? I'm about to replace my bike's chain and do a little bit of a drivetrain overhaul on my 105 5700 bike to eliminate some noises and mediocre shifting, I know the pulleys don't need to be replaced because they only have ~3,500 miles on them, but if there is a real improvement it's something to consider.
