"I suppose a full length sizer just means it sizes the full length of the case 'for width' and cannot adjust the case length as that involves cutting."
A FL sizer die will resize the webbing (body), neck diameter, and bump back the shoulder. It is your primary control mechanism for ensuring proper headspace in your chamber. RCBS makes a sizing die (X-Die) they claim will never require case trimming. You will find mixed reviews about the degree of success people have using that die. I do not recommend it for a beginner handloader.
"I might do the length sizing and neck sizing as the first two die operations which included popping the old primer..... "
One die or the other. You don't need or should not use both. The Collet neck die is the best design on the market for neck sizing but it will not affect the webbing or shoulder. That is why it will only work for brass that has been fired in your gun. Not all guns of the same cartridge have the same chamber dimensions. You have heard football is a game of inches, well handloading is a game of thousandths of inches.
"then switch turret heads and do the new primer, powder filling die , bullet seating die and crimping die
5 dies in all..."
You will find it best to keep everything on one turret but you will not need 5 dies because you only need one sizing die.
I find it very helpful to have a single stage press dedicated to brass sizing. You can see I have both the single stage and turret on my bench.
