You have two good choices for the money, that indicates you are doing you home work well.
Between the two mentioned, my vote is for Sony Alpha A350 because it has a larger sensor, is newer, you can use almost any older Minolta lenses on it that some come with very cheap price tag from ebay and likewise but with extremely fine features and sharpness that is expected from minolta, has mobile LCD which is quite a unique feature not seen even on most expensive D series of Canon or Nikon, and over all has a lot to offer given your needs. Sometimes at sales, Olympus comes with with better kid including two lens, etc etc but as such you don't go wrong with either choice and if money is not an issue then listen carefully to miketoll
