Clean the outside of the glass, don't use windex! Sometimes shooting at an angle helps get a clearer shot. Also, I don't know much about cameras but my Fujifilm E510 has a macro function. I get the best closeups when using the super macro feature with the flash off, all lights in the room off, and some patience!
I did some digging around and it appears your camera does have a macro mode. I can't read the horrible manual to figure out how to turn it on but heres the link:
Page 15 has all the modes and in the top right corner it should show if macro is enabled. HTH
P.S. - I'm assuming it is an A560?
