Well, it's likely that the switch vendor offers some tools.

Yes, those are reasonable starting points.

Sure. What's your budget?
Something like HP's OpenView (which I just learned was rebranded to "HP Network Management Center"), or Cisco's LAN Management stuff (evidently also rebranded) do all sorts of nice network discovery and autoconfig, routing/traffic bottleneck analysis, etc. They also cost 5 to 6-digit sums, but if you've got multiple WAN links between data centers to manage, or some complicated VM/cloud architecture, they're probably worth the price.
(Of course, if you've just got "a" meaning "one" switch to manage, that would be overkill.)
