Rick,
I'm not familiar with Photoshop elements. Look for something that says image size or similar function. In this command you should be able to set the size you would like. If you are shrinking the image there should be an option for bi-cubic sharper.
If you are still having issues I have photoShop CS4 and , live just just down the road from you on the south side of Temple. I'd be happy to resize for you.
