You do need a BES data plan in order to connect to a BES.

. As for whether they do or not you'll need to ask your BES admin. One of the points of BES is granular device management. Each company can define its own IT policies. There's no way that any of us can tell you what your company does and does not restrict on its BES.
I'd acutally recommend keeping all personal stuff off of a company BES-connected BB. Unless you're willing to share it with your company, keep it off their BES.
