Need help with a gesalt character

[Regissoma]

So I am making a gesalt character for a campaign character and need some help. What I have planned so far is a Dungeon Crasher Fighter 6/Warforged Juggernaut 5/X9//Crusader 20, but I have those 9 levels after WFJ to fill in. Now what should I put in for those 9 levels, and how would fraction saves work?

Extra things for the campaign:
Free racial feat or dragonmark
Free two skill feat i.e Athletics
Pathfinder feat progression

Edit:I might take Hidden Talent at level one and go into War Mind for sweeping strike and Expansion.

Now what should I put in for those 9 levels
Warblade.

and how would fraction saves work?
Every time you gain a level, if either or both classes has it as a good save, add 1/2, otherwise add 1/3. Keep track of the fractions, but always round down during gameplay.
