Dusty, If you are going to be carrying the laptop bag a far distance, I would definitely go with a backpack. Your shoulders will thank you later. The Tom Bihn Brain Bag (possibly with brain cells if you feel it is needed) would most likely accomodate everything. I am sure other will recommend Red Oxx stuff but I still like the TB stuff better (having owned both products). I bought the Brain Bag at some point but sent it back because it was too big for me.
Not exactly sure what you are looking for with the beer bottles.
