I use both. Lightroom is fantastic for organizing large amounts of
images. It also supports most global adjustments you'd normally want
to do on an image. But if you ever find yourself wanting to apply
something selectively to parts of the image, use layers, brushes, or
use a photoshop plugin, you'll need Photoshop. Do check out Photoshop
Elements. I haven't tried it myself, but people say it's very good and
supports many of the same operations as Photoshop. 

Adobe has fully functional 30 day trials of both available for
download. I recommend trying both.
