I think you should tackle one piece at a time. Its reall easy to tear stuff apart, than get overwhelmed.
Start by pulling the gas tank and seat. Than make note of how the throttle cables are routed. Pull the caps off the carbs, using the two phillips head screws on top. than pull the throttle and choke slides out by pulling straight up. They should just slide out.
To remove the carbs themselves, find the correct size allen wrench, and remove the intakes from the head. It is almost impossible to get the carbs off the intakes while its all on the bike. I had good luck grinding down the short end of the allen wrench a little bit to make it easier to get in to place. When replacing the carbs, do not over-tighten the nuts that hold the carbs to the intake. You could ruin your brand new carbs by bending the bodies of the carb.
When doing the wiring, its going to be hard to unplug one as you plug in the other. A good way to tackle this is with a roll of masking tape and a sharpie. Put a piece of tape on each side of the connector and label it. Than go a little at a time.
Start with those two. would be my advice. That way you dont get in so deep you forget what goes where and lose interest.

Welcome newbie. Great advice from Gahi about doing one task at a time. Get the interference out of the way (tank/seat) I have always had a shortened allen wrench for the carbs available. You will find lots of opinions in this forum but I would find a box for the Amals and buy a single Mikuni kit. You will still need the "special" allen wrench.
Plan out what you want to do with the wiring. There are some really neat electronic gizmos that can make wiring much simpler. Draw it out on paper first. Replacing the stock connectors will pay dividends later. They are famous for causing late night road side emergencies.
