Batch Create questions


I want to use Batch create to add a set of some 200 users and blogs.

First question is;

Can I switch off email notification as I don't want them to be notifed right now that they are added as users.

Second question:

I also have names - first and last, but don't see a way to add that information using Batch create.

Is there another plugin which will do this for me. Hoever the reason I liked Batch create was the idea that we could do the 200+ in one go.

thanks for a repsonse and advice on this..
