Do plus bonuses from those feats apply to my combat maneuver check when I spell sunder?

you receive a +2 bonus on checks made to sunder an item

But I'm not sundering an item, I'm sundering a spell effect.

the barbarian can attempt to sunder an ongoing spell effect by succeeding at a combat maneuver check

Not spell-like effect, spell-like ability effect, but spell effect.

the barbarian must make her combat maneuver check against a CMD of 15 plus the effect’s caster level

Moreover, it only specifies the "effect's cater level", but doesn't say anything about "CR of the effect’s creator" as in Eater of Magic, which works against spell-like abilities also.

So lurking around these forums I stumbled upon a fellow who said that you must be able to make additional AoOs, like per Combat Reflexes, to benefit from Fortuitous ability.
Why? It says that it grants you more AoOs. It doesn't say that enemies you hit with your AoO provoke additional AoO, it says you can make a second AoO.
Can someone explain? Because I can't really interpret it that way.
