I linked the .PSD file, but now that you've mentioned you have Elements, I guess that doesn't help. Processing is VERY important, but it's never going to be as easy battle when the original image is plagued by things you can't fix in post processing. I'm not trying to discourage you, I was just making sure you knew why the image won't ever be perfect.
The best thing you can do for yourself is work mostly on making an image that makes you think spending 30 minutes in Photoshop is really worth the effort. Eliminating distracting background elements, getting interaction with your subjects, minimizing the flashy look if at all possible, filling the frame with your subject, getting correct exposure and white balance, etc. The processing on those kinds of images is a much easier place to start.
After you've processed great images for a while, fixing bad ones isn't such a daunting task.
