WP is very versatile; but also easy to get confused due to the amount of choice. you must also be careful of spammer/hackers constantly; on a different CMS I misconfigured something and Chinese were posting ads for multi species diet pills (I kid you not; they were apparently suitable for both humans and cats!)
What exactly do you want to do with WP, and what level of access do you have to the server running it? in many cases your hosting company makes it easier for the installation (I confess I've never successfully installed it from command line anyway)
