One difference is you'll probably swing an 09 for cheaper than an 08, since the 09s don't have that numbered dashboard plaque that somehow, according to dealers, adds at least an additional $10,000 to the car's value...
Seriously, the LSD will be standard on the 6-speed cars (and I'm guessing an option on the automatics, although Dodge needs their heads examined for not including it on all V8 models, regardless of whether they're a 6-speed or automatic). Also TorRed will be another color choice in 09.
As far as the stripe difference, I personally haven't heard of any difference, but maybe someone else can set us straight on this one...
