There is no specific rule for that.

For April appt, better to send more recent documents.

Around 1 week to get passport back.

I second Immihelp statement. I booked the appointment for my mom in Nov, available in Feb. The first set of papers (in Nov) were discarded and a fresh set were sent, and its succesful. So, I advise you to send a latest set of papers to avoid some kinds of problems
Thanks,
