1) Reliability? Variable. It depends where you are and what problems arise (surprise!). Beware that businesses are given a Super Hub 1 which CANNOT be put into modem mode, and that wireless from the Super Hub 1 is poor (I under-exaggerate).
2) Traffic Shaping - I would say that even if it exists for businesses you are unlikely to be affected if all you do is browsing and VOIP.
3) Virgin Media broadband is Virgin Media. Full stop.
4) If you're a business you can't be a consumer. Business users pay more and get a (somewhat) better customer/engineering service.
Note that you will get a maximum of 50 Mbps down, and 3 Mbps (or perhaps 5 in some rare circumstances) up. The up-speed may be a problem (but not with what you're doing), however it tends to be fairly close to what's promised.
I think your contract will be for 18 months, during which time the monthly cost will probably/possibly increase somewhat. Price rises tend to be annual and/or random!
Think where you will want them to install the Super Hub, and/or be prepared for the cost of Wireless Access Point(s). Any need for these depends on the size, number of floors, etc, which you occupy.
A final point - you can order more than 1 broadband line
! (If you want higher throughput.)
