All great questions. I can't comment on the Bose specifically, but I would imagine the Bose system is identical whether optioned for the LT or standard in the Premier.
As for charging options at home, a 220V line would need to be installed. Most seem to go with a 50 amp dryer style socket (14-50). Clipper creek seems to be the preferred manufacturer for home EVSE's and their 32 amp model would definitely be more than enough for the Volt, and sufficient for future use as well. The HCS-40P would be a good all around unit to have and runs about $600. They are definitely easily available online and can be found on most any EVSE/EV based website and even available on Amazon.
*One note on the EVSE that comes standard with the Gen2 volt is that it can actually do L2 charging (220V) with only a plug adapter, so in that event, you can just have the 220 line installed and build an adapter plug to convert the 5-15 plug on the EVSE to whatever style plug you have installed for the 220 line. It's SLIGHTLY slower than other L2 units because it's limited to 12A but it will cut your charging time to less than half that of 120V.
Long trips in the Volt are wonderful. I have a Gen 1 and have taken it on a 300 mile drive to Vegas a couple times and find it to be quite comfortable and still have about 1/4 of a tank left or just slightly less. I just jump in and go.
There is an option called the VoltShelf offered by Scarlett1 that might be exactly what you're looking for. He has some very nice volt items he custom builds.
As for negotiating with the salesperson, make it known up front that you have no interest in any extras. It's standard practice for them to offer extras that cost them little/nothing for insane prices and usually only amounts to someone going and grabbing an aerosol can of scotch-guard that cost $15 and charging you $300.
