I'd recommend using categories to sort your contacts. If you don't want your company/BES admin to have access to your personal contacts then you really shouldn't have them on your company BB at all.
I concur on the tip as well. On my Pearl I "CAN" save contacts to the SIM card 1-at-a-time, which is painful. This is something I'd like for RIM to adjust in the next series of firmware updates for both 8100/8800 - saving contacts to a SIM card should've be perceived as a security risk, to me personally, but hey at least we can now.
Check you local store and see if you can get contacts copied from a previous SIM card onto a new one with a SIM-to-SIM coping device.
