What I would do would let everyone have free access to what was allowed. If there was something i thought was rare enough or overpowered enough to not allow into general population i would simply disallow it as a PC option.
For cases where you must have something higher powered keep it as an NPC; sept elders NPCs, Prince and Primogen NPCs. As far as IC leadership among the PCs I am a firm believer in let the PCs sort it out, don't give anyone extra stats or more OOC authority. If they use said IC position in ways detrimental to the game give them a slap on the wrist on the first instances and a boot in the ass on the second.
Of course I have never really seen IC or OOC faction leadership as a big thing, for the most part IC factions tend to be reasons you get stuck in boring ass meeting scenes and then rarely actually come up in the course of rp.
