Osama,

there is heaps of software out there that can do this, including some freeware

PRTG is pretty good, you can use LAN sweeper, and do a network discovery based on IP addresses.

you can use Solarwinds as well

1 >Please try running Nmap in your network. you will get the topology.

2> For - Monitoring your network for status change and services you can use NAGIOS an open source tool - this require some Linux knowledge.

3 > password change in router depends on model you are using. What is cisco hardware model and os version?
