Re: Whats going wrong??
If you are viewing your image at 33% or 67% of its size, it will introduce jagged edges/contours.
Try viewing you image at either (in %) 12.5, 25, 50, 100.
As for the noise, it may be caused by underexposure at the time of capture. If you tried to up the exposure (or adjusted curve upwards) in post-processing to compensate, it will introduce noise.

(photoshop elements is more than fine for opening/viewing your pics, but try and stick to the % indicated above when assessing your work)
