Just use your loader to brow up the logs as you keep cutting off the pile, that way most will be off the ground until the pile is almost gone...flip the last few over the last log on the ground then cut that up, if the saw is dulled on the last one your on your way home anyway.
Throw the short pieces in the bucket as you cut along and dump em into your truck or that other thing you mentioned for hauling the firewood out. That will keep them clear of the long wood.
I think you have all the gear you need.. anyway you do it will be the usual sweat shop work...
I used to pick up a grapple full with the pulp loader, hang it over the truck box and cut right into the box, drawback was you got all the sawdust with the load.
Happy grinding
