Member Registration

Hi, 
I want to build model for user registration. 
User registration shoul go in following order:
1. User enters his data in registration form (form has about 15-20 fields because its for like corporate members, they also enter corporate info in form)
2. We send email to user to confirm his email/registration
3. After user confirms his registration his registration is approved

My problem is 
1. where I should kep those 15-20 field of member until it is approved. in the same table as approved members? 

 Also member password recovery link is sent by email, I need to keep password recovery info somewhere in db. 
I dont know where to keep this info in user table or in separate table?
