Are these tires too big?

Check for yourself. Compare the total diameter and the width with 225/50R16, a know tight fit. The lowering springs may be a problem, but others have posted that the 225/50R16 works with lowering springs.

Wheel offset also makes a difference.

how much of a difference does tire size make in acceleration? Say going from a 40 to a 45, I am running a 55 right now, but my friend just went from a 40 to a 45 and just wondered how much slower that would make him?

A smaller diameter tire is like slightly lowering the gear ratio and will usually provide slightly quicker acceleration.
As to how much it will throw off the speedo, use a tire calculator. Here is one:

Does it also throw off the odometer? Thanks.

Check the link. The tire calculator will give you the tire diameter difference, width difference, and speedo difference.
