I'll go ahead and steal your question for a bit:

If an Alchemist who has a Vestigial Arm holds a shield with his extra arm, does he still get the penalties if he has no proficiency with it? Does he get thrown off-balance despite not actually using it during the fight? If he doesn't, what happens to his AC?

Now let's say that the Alchemist in question does have proficiency, can he now use both a shield and a 2-handed weapon at no penalty? What about the Str/Power Attack bonuses? Do they still count as using 2 hands?
