With regards to your ability to setup at home, you can do it. It shouldn't be that hard. Naked Whiz just did a write up on their page that might be good assistance (beyond what you might have read on these forums).
As for the hotspot, if you can log into some sort of webpage for the hotspot, it might be configurable. Otherwise, call verizon and ask for help.
