advice to fully utilized OpManager's capabilities?

hi there,

OpManager build 11400

as the subject says.
We currently have OpManager up and running. We've set up a few notifications profile but that's about it.
We need advice on a few things to make use of its full capabilities such as:

real-time monitoring of server/switch network CPU/interface
set threshold of network port's utilization (so we're informed if there's congestion)
general advice on how to answer the usual "the network today is a bit slow, isn't it?"
and other nice tips and tricks

is this forum a good place to ask these?
Or is there a more appropriate place?
(this is not a technical issue but more of requesting a how-to advice)

thank you in advance!
