Since I've started on level 8 (And we're getting lots of XP each game) I did this:
Paladin Hospitaler - 4
Monk of the Lotus - 3
Oracle - 1
With 30 points to ability scores (It works with 25 too) I got Wisdom and Charisma to 18 (Both 16 +2 from human +2 from atribute bonus on 4 and 8)
Got +4 on anything from Monk (Bonus AC, Saves for Touch of Serenity and "to Hit" with Guided Hand)
Got +4 on anthing from Paladin (Channels, Smite, Saves etc)
Going to get Osyluth Guile on Level 9 (Since I can't get earlier); together with my first level on CoI.

BTW, what are your thoughts on going pure Snake style? Buff sense motive and completely forget about armor!
