Wow, no offense but your post is hard to understand. I think I got the jist of it though.
If your TV has component inputs, you likely have an HD TV. Not 100% though. My brother has a Sony Wega 26" CRT TV which has component jacks, but it's NOT HD compliant.
Now, all that said: The Wii through components will output 720x480P and standard digital images. You should be ok to use component cables.
However, don't buy them from BB. Way too expensive. You can get a set for $10-$20us which are just as good (even on my 55" HD-RPTV).
