The first (left most) index is the row, the middle index is the column, and the last (right most) index is the color. Specify those to get the value of a certain color channel at a certain location:
blueValue = rgbImage(row, column, 3); % Extract the blue value at this row,column location.

I don't know. Just look around - there's medfilt2(), conv2(), imfilter(), etc.
