My problem with the point system is that it inherently increases the flexibility of the most flexible characters to begin with, and I don't like widening the gap. But that's just me.
Q180: Can a reserve feat fuel a Su ability? Such as...Arcane Fire?
Arcane fire specifies that it requires a 9th level slot to gain it, and that the use burns up the energy of a spell to manifest it, so I would say no, since the Reserve Feats are (Su)'s and not spells. If Reserve feats were (Sp)'s I'd say it'd probably work, but that's just my gut instinct.
