RE: changeing fuse box to circuit breaker box

It doesn't matter. You don't need a breaker in the subpanel (the one replacing the fusebox) at all. Anything 100A or more is legal, but the extra doesn't get you a nything.

RE: changeing fuse box to circuit breaker box

If they didn't do it at the upgrade to 200 amps. You will for sure now need to make sure the sub panel is fed with a 4-wire feed (2 hots, neutral, and a ground wire). The neutrals and grounds in the fuse box/ your new sub panel, have to be on separate terminal bars in this case.
