The main reason I bought this set up was for the case, I also saw the extras and thought what the heck.
For a DS Lite case it's actually pretty nice, fits the DS in one pocket and the in the side there's room for 3-6 DS games (bout 2 in each pocket) a screen cloth and the big pen, maybe the headphones.
The headphones are pretty cheap, I use my own sony's.
The rest of the stuff that comes with the kit is mostly icing with the exception of the screen covers, those are another nice addition and if you read the labels before you put them on and are careful with your application they should go on nicely.
I doubt I'll use the car charger but it's nice to have.
The pen is actually harder to use in my opinion and I have big hands.
The rest of the stuff is just fluff, I may use that extra case in the future but the other things like the screen cleaner pad are just silly, the pad is backed with plastic and is just too small to be of any use after a few swipes, you can get a lens cloth cheap just about anywhere.

Again, for the case and the screen covers I felt like this was a good deal, the rest I probably won't get much use out of but it was cool to get.

Oh I also have a hard shell on my DS lite and it still fits in the case. Theres one corner that the zipper doesnt like to go around but with some wiggling and finesse I can seal it up fine, with out the shell the DS Lite fits really nicely.
