My BooqBag Sleeve from www.booqbags.com fits the thing like a glove, and has excellent protection. The outside is extremely tough, while the inside features an extremely soft place the MBP to rest without getting any scratches. It was a bit pricey, but I would highly recommend it.
I like my Targus Laptop Bag, it only costs $25 and it fits my MacBook Pro pretty well and the front compartment is spacious enough for my extra battery, iPod, and USB Flash Drive. The link for the laptop bag is here. I recommend the iSkin for a keyboard cover, I use it and it's great. I haven't used a trackpad cover though.
I just ordered a case for my SR MBP from Tom Bihn. The Brain Cell, which comes in both vertical and horizontal orientations. http://www.tombihn.com/Merchant2/merchant.mvc?Screen=PROD&Store_Code=001&Product_Code=TB0390
I really like the hard outer shell along with the dense but soft protection inside. I have envied someone else's TB case for a while and finally decided to get one for myself.
Has anyone used the Speck See Thru shells? I'm considering getting a Speck shell since it should protect the outside of my laptop when I'm using it or it's not in a bag.
A friend of mine has the Tucano "second skin" microfiber sleeve. It's great protection from scratches and scuffs. It fits like a glove and hardly changes the dimentions of the laptop...
If you need better shock protection you can still put it into a more protective backpack (like the crumpler)...

I'm using them right now, it does protect the laptop very well when it's out of the bag. The only downside is that it came very scratched up, but I got them 30% cheaper than retail, so I can't complain.
