WAN, LAN and WiFi analysis

I would like to perform an Analysis for our WAN, LAN and wifi.  More specifically I would like to understand:
a. What is my current connection capability (What is 100% of my WAN, Wifi and LAN)
b. What is my max, average and standard deviation of the usage during "office hours"

Is there a tool that would help me collect and analyze this information and makes it easy to read and digest to non-technical people?

My topology is:
AT&T fiber (10mb/10mb) connection
Cisco RV320 router
Two Cisco SG300 52 port  
One Cisco SG10P
Two Cisco WAP321access points
Four Window Servers
40 desktops
10 laptops
5 tablets
