I currently have a 4 zone sprinkler system, but now need to add an additional zone or two....all 4 existing zones are maxed out. Can anybody start me off on how to do this. Over the last year, I've moved many heads, and feel pretty confident, I can add a zone if given the proper instructions

If you have a 4 zone system, that means you have 4 valves for each zone. So, to add a zone, you have to add a valve. Valves are located at the water source and are hooked up in a manifold pattern. This is one pipe coming in and split to each valve. Then each valve has a pipe going out to each zone.
Adding a valve to PVC or plastic pipe is done by cutting the pipe between valves and gluing and adding the additional valve. This can also be done at the end or beginning.
Adding a valve to metal pipe is similar but more difficult in that you have to determine in advance the amount and size of pipe in advance.
Hooking up the valve to a controller or timer is a matter of either using unused conductors in the existing wire or running new wire.
Your existing controller or timer will have to have an additional hookup and control for the new valve.
If your valves are manual (not electronic or timed) then you don't need the controller or timer or wire since you'll manually turn it on or off.
Option:
You may be able to add one or two valves to an existing "leg" or zone after the zone's valve using the same procedure as above, however your pressure and volume will be reduced.
Just about every home improvement store will have a pretty good installation guide for sprinkler systems that will show you examples, how to calculate gpm and pressure.
