NO doubt, absolutely yes! Get the full package and you'll never look back. I'm fairly new to the skinning scene myself and have thoroughly enjoyed the full version of Object Desktop, having begun much as you have, with changing icons, cursors and wallpapers, etc. Upon discovering Stardock and Wincustomize, my computing experience has immensely improved and I could never go back to the basic Windows appearance.
There's so much to learn here, but hey, that's the fun of it.
