help wiring a 100A panel box

[mhgcsuper]

This is my first time posting and I found this site at the right time. I bought the HOM612L100F 100A box Homeline by Square D. I want to wire it in my shed and I am coming from the meter base (about 5 ft. away) not a main panel. This box will be the main panel for the shed. What kind of wire do I need to go from the meter socket to the box and do I hook the bare grounds to the neutral block as well as the white wires. The meter socket is grounded and I also have a ground rod outside that the old box was grounded to. Does the box need to be grounded to that ground rod also. Please direct me on details of what I need to do. I am pretty knowledgeable about electricity and love DIY stuff. The old panel box caught on fire last Friday and obviously had a problem. I DID NOT wire that box but I am leary of putting it back like it was. Just want to get the good advice that I have read on here to make sure not to repeat the fire issue. Thanks for any info.

A picture is worth a thousand words so there's a diagram attached. some jurisdictions make you put the driven ground rod cable into the meter socket, others let you ground the neutral bus in the panelbox. your panelbox uses one of two grounding methods. either a long screw that goes through the neutral bus to the panel metal back or a jumper that goes into one of the neutral holes.
The size cable to use is #2-3 SEU cable Aluminum. Use non weather-tight connectors at the meter and panelbox. twist the wrapped ground together and use plenty of anti-oxidant at the terminations and torque the screw to specs found on the panelbox cover instructions. let it rest a bit then re-torque the connections. you'll get another half turn most cases.

First off, can we assume the power is OFF??? I hope so.
If not then you need to get the POCO out to kill power to the meter, AND to open the meter, so you can work on it.
They can also tell you THEIR requirements for where the grounding electrode conductor goes.

*EDIT* (Sorry Hazee, I misread the post.)

You WILL have to get this inspected.
