I don't think Precocious Apprentice fills the "being able to cast 2nd level spells" requirement, since the feat itself mentions you don't have that ability.
Whether Precocious Apprentice is a valid way to enter a theurge prc or not has been debated ad nauseum on just about every D&D message board in existence.
I used to take the position that it didn't quality the pc for early entry, but I've seen (and played) enough theurge types that I don't see what the harm would be in allowing it.
Unless you are using Ur-Priest as your divine half of the theurge progression, the wizard/cleric, wizard/druid, etc advancement really lags behind the single class casters when it comes to highest level spells available to cast. I do understand that is the draw back of progressing in two classes, but it almost makes the theurge unpalatable.
In my campaign, I do let the players use Precocious Apprentice as early entry.
