What's the default way to determine a creature's CL for its SLAs?
Normally, a Succubus's SLAs are CL12. What's her CL if she gains class levels?
In 3.5, a Hound Archon Hero's caster level didn't change when it gained class levels, but a Pathfinder Drow's SLAs have a CL equal to their class level.
in 3.5 a drows caster level was equal to its total class levels as well... this is a special ability of Drow, not of SLA caster levels in general.
Class levels on creatures with racial hit-dice generally do not increase caster level (I'm sure there are exceptions).
Adding racial HD probably should, but I don't think there's a rule on it.

There was a recent clarification about half-dragon's breath attack intentionally being based on racial HD, not class HD. I would say unless the SLA specifically says it is based on class levels, then it isn't.
The thread is here.
When I create monsters (a favorite pastime of mine) I tend to use the creatures HD or the minimum to cast cleric/druid/wizard level that would be needed to cast the highest level spell from among the spell like abilities, which ever is higher to set the caster level of the spell-like abilities.
