Noob Question: Building a Sword Saint

I am new to Pathfinder, and relatively new to Fantasy Grounds.

I am trying to build a dex based elven Kensai.

I know it can be built by hand but i dont know FG well enough to know how to build it by hand.

The class is in Ultimate Magic, the Archetype is in Ultimate Combat.

If i buy Ultimate Combat will i have the majority of my needs to build covered or do i need to buy both?

If you don't mind the load wait time, this archetype was built as a draggable class in my Classes and Archetypes Module.
