If you can somehow get sneak attack damage !d6 needed), Black Flame Zealot.<br/><br/>Paragnostic Apostle has full casting, good skills, and class features all based on being a skill monkey (especially knowledge). Easy to qualify for too.<br/><br/>If you can get the race req dropped I bet Seeker of the Misty Isle would be EXACTLY what you want.<br/><br/>Again take out the racial connotation and Divine Prankster would be a great fit.<br/><br/>Change the alignment requirement and Shadowbane Stalker works great. (still need 1d6 sneak attack though)<br/><br/>SKypleged fits you well if you remove the raptoran  prereq.<br/><br/><br/>If the skill points aren't something you MUST have Contemplative or Divine Oracle are great choices.<br/><br/><br/>Edit: Also Urban savant has a lot of what you want.<br/><br/><br/>
