JBossAS and JBoss Application Server is the same thing. JBoss Web is the web container of JBoss, based on the code of apache tomcat + extensions. JBoss Web runs inside the JBossAS runtime, so when you "run" JBoss Web you are essentially running JBossAS. I believe there is also a "standalone" bundle of JBoss Web that is essentially a JBoss AS configuration that includes only the minimum modules required to run JBoss Web.
