The log files managed by JBossAS are the console log (which displays in the window you used to run JBoss AS), and the *.log files in the server/xxx/log directory. The other logs (derby.log, localDB.log) are managed by the Derby and Hypersonic database. You can change log levels by editing the server/xxx/conf/jboss-log4j.properties file. And valid log4j configuration settings will work, though note that JBoss AS defines its own appender classes.
