Skully,
i'm not sure i understand your first question on the multi head geometires, but you can apply as many tools as you like to any aparticular geometery.
when copying tooling i always select as origional with tool sorting, this will reduce the amout of tool changes or the need to move the tools. keep inmind you can't edit copied tools. if you use the same tools and methods often create a maching style.
the Onsrud techs are very good, at one point and time Onsrud had more certified alpa cam trainers than Plaint/alpha cam did. quite a few of them worked for planit. it maybe be worth your while to go back to Onsrud for more training.
i'll try to help where i can,
