A tidbit re Spellgems:

Spell Chip modules for your computer are a great way to save a few credits for spells you might want to cast multiple times in your career, but not often enough to burn a spells known pick on. The initial module costs 10% more than the base Spell Gem, but you can reload the spell for 10% less; basically, the first time you reload it you break even, and it's 10% off from then on. 

I'm not sure whether using a Spell Chip would save you from AoOs for spell casting; using a Spell Gem seems to basically be casting a spell, but a Spell Chip might fall under using a device.

The other reason to pick up a Spell Chip is for the Sweet, sweet +2 competence bonus when using a skill related to the spell you cast it on. Comprehend Languages looks to be one that would benefit from this bonus....
