Q1 - Grafana in a business. So far I've got data coming from fiber switches via snmp, Nimble via API & Powershell, a few Telegraf agents, several MS SQL sources, Avamar via Postgresql, SCOM, and Solarwinds.

I plan on getting metrics from Pure, Isilon, Extrahop, NetMRI, BMC Remedy, and practically any other source that they give me access to. My bosses are pretty excited at the possibilities!

Q2 - Graphite in Influx. I've got it set up right now as an Influx data source so I see the full graphite metric string. But I lose the ability to use Grafana's graphite query builder. Is there a trick to get Grafana to access it as a Graphite data source?

EDIT: I finally discovered this page which gives a couple examples on filters and templates (I know, RTFM, right?) which I had overlooked. This solved a chunk of my problems when having graphite metrics stored in Influx, and then displaying with Grafana.
