Yeah that should be fine, just make sure you get the component cables for the Wii. The Nintendo brand should be fine, I threw down the money for the 'almighty' psyclone brand comp cables when I worked at Best Buy, but there probably isn't a real big difference. It's only 480p either way.
Just my opnion but that is alot for a 19 inch. You can get 19 inch comp monitors for less then 200 easy and it has the same quality. Also friends of mine have bought 52 inch Dlp monitors for only 800. Id say look for a better deal then that.
I've seen that model in the stores and it produces an awesome picture but I'd go up to a larger size if you could afford it. My LCD HDTV is also a Samsung.
