I fiddled around with this and it's safe to kill everything. The vital processes will just start right up again. socialnetwork.provider and provider.weather are, I'm assuming, to do with Facebook/Google integration and weather widget/applications respectively. If you're going to be killing processes regularly, I'd suggest you put touchflo and touch input in the ignore list, as they need to be running constantly for the UI to work. You can kill them, but the phone will hang for a few seconds while they restart.
