How do I set my nickname?
Type "/nick [YourNicknameHere]".

My nickname keeps getting reset to something like "Unknown256"!
This only happens when you're using a nickname that's already registered by someone else. You need to choose a more unique nickname.

How do I keep others from using my nickname?
You need to register your nickname. To do this, type "/msg NickServ register [YourPassword] [YourEmail]". You should then get an email. Follow the instructions it sends you, and you're set!
