Generally, it is very hard to picture the gap between sensor sizing purely by reading specs. The photograph underneath might offer you a more clear sense of the sensor sizing in the 9000 and A55.
All in all, both the cameras enjoy different megapixel count and different sensor sizing. The 9000 with its tinier sensor is going to make shooting shallower depth of field more difficult and the Sony A55 will offer greater detail with its extra 4MP. Greater resolution will help you crop photos far more aggressively. The older 9000 is going to be behind with regard to sensor technology.
