The unique components of RWAN (which, as a bundle stopped availability in Nov 2004) are ACL Manager (ACLM) and Internetwork Performance Monitor (IPM). IPM went to the LMS 2.5 bundle (Feb 2005). ACLM is being absorbed by Cisco Security Manager (CSM) and CiscoWorks VPN Management Solution (VMS), although you still can get ACLM stand-alone if you need it (please get with your field sales SE).
You're asking for several management functions that aren't addressed in just one package.
You could use CiscoWorks Qos Policy Manager (QPM) to configure and monitor QoS policies.
CPU utilization and uptime would be a standard performance monitoring suite - HP Openview Network Node Manager, Concord, InfoVista, Cricket, Cacti, MRTG/RRDTool, etc, etc. Lots of choices in the performance monitoring space. CiscoWorks has the CiscoView application that provides a GUI of a chassis and that can be used for real-time monitoring of key performance metrics like CPU, memory, interface utilization...even temperature for devices that support environmental monitoring. However, CiscoView is NOT storing these metrics for long-term analysis/review/trending. That's why something like Concord/Infovista,etc,etc is necessary.
CiscoWorks LMS 2.5 with the RME 4.0 application suite would be able to push configs and software images. It will also audit network changes - if you point your Syslog event messages at the CiscoWorks RME server, then it can get those config, software image and inventory changes (module insert/removal) in near real-time.
RME can also keep past revisions/history of configs.
