Urban ranger/aristocrat--Ranger isn't listed as an option for aristocratic background, and I can't find anything that says that the listed skills are treated as class skills; the table merely requires you to spend points on them.
Education--The Education feat is not really right for the character. Knowledge Nobility is the only knowledge skill he should have.
I already knew about Marshal. I may end up using this option... He won't be playing to the strengths of the class because his Charisma isn't very good, but the Diplomacy bonus is still nice.
