Member Registration

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

Using the same table with an additional "is_approved" flag is doable, but using a separate table is better.

 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?

Separate table.
