1) yes, manually over-write them, then restart or SIGHUP your snort daemon. Don't forget to check the snort.conf file and update the variables in the new one.
2) If you were auto-updating signatures, what would happen if someone managed to hack the snort rule server and put up an empty signature list.. you'd be unprotected. Manual install implies some level of quick "is this list reasonable" checking on your part.
Malicious intent aside, how would you sensibly auto-update? the snort.conf file needs edits to have your IP address ranges so you can't use the new one as-is. Also, the number of .rules files included by snort.conf varies, so you can't use your old one.
Besides all that, the default ruleset is often not exactly what you want. I for one have to tweak a few rules out (mostly ICMP ones) or I get flooded, and add a few custom rules of my own to local.rules based on the structure of the network here. Once you have a feel for snort you'll probably find tweaks of your own.

If I'm to update it manually - what should I do - download it and simply overwrite existing snort rules files? Why I shouldn't update it automatically? (It's good that I shouldn't cause I don't know how :-)
