Arcane vs Divine doesn't matter as much as a maxed spellcraft check. (since they could create anything that isn't spell trigger or spell completion and just add +5 to the DC if it's an arcane spell)
Yes crafting feats are very useful, especially Wondrous Item, and Magic Arms and Armor.
Note that Craft Wands is a bit more useful for divine casters than most arcane ones. Being able to produce cheap wands of stock low-level buff and healing spells (bless, cure light wounds, longstrider, aid, barkskin, lesser restoration, etc.) can really help out a party, even at higher levels. It's still Craft Wondrous Item >> Craft Magic Arms and Armor > Craft Wand > Brew Potion/Scribe Scroll for overall utility to the party.
You do need to prepare/know the spell to create wands: "Creating Wands ...The creator must have prepared the spell to be stored (or must know the spell, in the case of a sorcerer or bard)... The act of working on the wand triggers the prepared spell, making it unavailable for casting during each day devoted to the wand's creation. (That is, that spell slot is expended from the caster's currently prepared spells, just as if it had been cast.)" Core Rulebook, pg. 553. This makes clerics and druids better choices than oracles and inquisitors if you want to take Craft Wand.
