Bag, Sleeve, and mice suggestions!

I just ordered my xps 140 (yay!!) It should be here in a couple weeks, so in the meantime, i need to have some accesories waiting for her when she gets here.
I'll be taking it to school everyday and hence need a nice bag for it. I'm looking for a backpack style one, but not one that looks too dorky. There's like a million out there, so i need some suggestion on ones that ya'll have found that you like. It's a 14.1" screen. Which one will fit it best?
Also, should i look into buying a sleeve as well? I havent really researched them out as much. I would use it basically as extra padding inside the bag i think. What ya'll think? and what it a good sleeve that will fit my lappy?
I also need some input on some good laptop mice. It will mostly be used in my house so i dont need a SUPER small one, but small is nice. (i still want comfort) I want wireless, and a tilt wheel (one that can scroll horizontally as well) would be nice. Which ones do you think would fit my nececities??
Thanks in advance, look forward to some feedback.

What's your budget for the bag? I like the Sumdex, Tom Bihn and Crumpler, if you're concerned about style. Some come with a sleeve, some don't, you probably don't need to buy one though unless you intend to carry the notebook on its own. I prefer the Sumdex sleeves the most.

As for a mouse, check some of the other threads that have discussed this already and post any specific questions you might have.

 

Ok, so i think i've narrowed it down to a couple. I've heard good things about teh logitech v200 mouse. I like the fact that it has a tilt wheel and has a scroll that "clicks". I've heard that the ms wireless notebook optical mouse has a pretty shabby distance that it works at. I looked at the ms6000 today at bestbuy. How's the distance for teh ms6000? Does it "click" as you scroll?
One last question...does anyone know yet when the v400 is coming out??? if its soon, i might wait for it, if not, i'll prolly get one of these other two.
Thanks ya'll.
