Application Manager how to fit to my environment

I'm going to test application manager (free edition) to get data about performance counters such as system cpu usage(processor time), application memory usage (process working set, etc.), disk usage, threads, bandwidth usage.
Actually our applications under test are running in JBoss A.S. 3.2.3 using JVM 1.4.2_15 on O.S. Windows 2003 Server + SP2 managing 2 CPU plus 2 virtual CPU with hyperthraeding. Also we would monitor the degradation of processing performance, if exists, of our implemented EJBeans (in terms of memory consumption, reaponse time), the JMS Topic related to queued messages, the database transactions to MS-SQL Server 2005 (average transaction time, number of timeout, number of deadlock).
Normally we have the Server PC running all of those, and a Client PC (Windows XP + SP2) in an Laboratory LAN that can be accessed by a gateway from our enterprise LAN.
Where have I to deploy Application Manager?
Can Application Manager afford the cpmpletion od these tasks? Do I need Enterprise edition or higher?
Could you give me some drift to solve my questions?
Thanks.
