Ok, so I've been looking at LCD TVs and most of them are HD ready but it says they need HDTV source (or something). So, if I were to play a HD game would it be in HD or would I need the HDTV source to get it to work?
You'll also probably need "HD cables" for whichever device you're trying to use in HD. Currently the only "standard" console package that comes with HD cables is the Xbox 360 Pro package. For other consoles you may find yourself stuck paying an extra $20-40.
