The inno home package includes almost everything that you'll need: remote, home dock, home antenna, power adapter, travel adapter, rca/usb cable, battery and ear buds (so-so). The car kit is sold separately for about 60-70 bucks. In terms of reception on the move (outdoors), I do not have any complains. The built in antenna works really good. However, if you're in the subway, or walking through a tunnel, then the signal will fade. For this scenario, you'll need antenna headphones.
I have a windowless office and it's located almost in the center of the building. It took me a while to find the perfect spot in my office to put the antenna. After a few tries I found the perfect location. The antenna cable is long enough that I was able stick it (with masking tape) on the wall close to the ceiling about 8 feet from the floor where the signal is excellent(3 bars). At home, I don't think you'll have any trouble with reception.
It'll be perfect in a car. Just put the antenna on the dash. I have an older one in my car (not portable) and I never had problem with losing signal, except in tunnels.
One downside as you know is it's subscription. I'm paying 12.99/month for my older unit and 6.99 for the inno. But I think it's worth it. I like listening to a variety of musical genre and sat radio is just perfect. And I can listen to the SF giants games anywhere I am.
