The feat is good, and seems not overpowered, though... Perhaps are 2 free Class Skills not appropriate...
Here is another suggestion:
Arcane Dabbling / Templar Training
Prerequisite: none (or some Background Information)
Description: You have undergone a certain training in arcane or divine spellcasting, though you never went deep enough to understand all the concepts or learn to really cast the more powerful spells.
Benefit:
You can cast 3 cantrips or 3 orisions with an effective caster level 1, using your Intelligence (cantrips) or your Wisdom Score (orision) as Spellcaster ability score. You can cast each once per day.
Additionally, you gain +2 on some Spellcraft & Deciper Script Checks, and a +2 bonus on knowledge(arcana) for arcane dabbling or knowledge (religion) for Templar Training
When you choose arcane dabbling, you gain the bonus to Spellcraft & Deciper Script when you use the skill on arcane spells & scrolls, if you choose Templar Training you gain the bonus on using the skills on divine spells & scrolls.
If you chose to take a spell caster class using spells of the chosen type, you are considerd having spell mastery in them (arcane dabbling and wizards), or know the spell additionaly to other cantrips you know (arcane dabbling and sorcerer or bards) or be able to spontaneously cast the spells (Templar Training with Clerics, Druids, Paladins and Rangers), but you cannot add the spell to your normal amount of spells per day.
You still keep the bonus to the skills.
Arcane Dabbler is a fine name as well.
