you would need both the kit from ebay, and the second screen you linked for a plug-and-play solution-- the dd lilliput only adapts the screen to double din standards..
though, you could buy the first screen, and then fabricate your own dash bezel(there is a sticky in the fab section on this)
there is always more then one way to do it, it is up to you to decide which way is best for you.
also, if you wanted to do it for a little cheaper, the bezel that is used on the screen in the second link is the double din screen kit from www.bybyte.com (around $20-30)
you could take the first screen, and install it in the double din bezel yourself, but you will void the warranty, and there is always the risk of damaging the screen, but you would save a couple bucks, and learn a little in the process..
and, being that you are asking it here, i should also remind you that mp3car sells the same screens, and can also offer the install kit-- like the one you located in ebay...
