Best bet is to start by disabling/enabling the major categories that you
might need. Also look at bleedingthreats.net for a complementary ruleset
to the stock sets.

Then look at what hits you get and make sure your sensor can handle the
load. Then start en/disabling individual rules that are of interest to you.

You can en/disable categories of rules in your snort.conf. Individual
rules in the individual ruleset file most likely in your rules/ dir.

It can do both. Stock it'll be just monitoring. To block you have to get
more complex. Go inline, use flexresponse, or something like snortsam
(snortsam.net).

It'll do that on it's own, but ya generally so.
