asp.net, c#

1. Got a project to create web-based application to allow user enter information for car insurance quote, it will have over 200+ parameters that we need to save like address, car information, total driver count...and etc., and they all need to be saved into the database.
Instead of create 200+ fields in the table, do any experts have any other / better solution?

2. The application involve at least 5 steps to complete the quote, do any experts know any better asp.net form generator that we can code instead of using asp.net wizard or panel?
remember we have to allow client update the original information as well. we hope to use same UI to avoid extra coding.

Thanks
