Be cautious about changing titles. Big changes, esp. to entire sections of websites, can cause SERP problems. I make minor changes (e.g., adding the year) without problems.
Sometimes you're better off creating a new page with old content than keeping the old page and changing the title.
I like putting the site domain at the end unless it's a short or kick-@ss domain name!
