High priority feats for me to get are Find Familiar, Landlord, and Item Familiar, (Corpsecrafter would be a major boon if it worked on my spawn rather then what i make from spells)
Feats I have: Spellcasting Prodigy, A Feast Unknown, Leadership, Undead Leadership,
Feats from flaws: Path of Blood, Improved Cohort.
Improved Cohort could be postponed for one level, my cohorts would start one level lower then but they could gain it as soon as I hit 12 and take that feat.
Spellcasting Prodigy isn't 100% necessary but it's hard to justify giving up a feat thats +1 dc for all spells and more spells per day.
