I-129f validity

[InsomniacDoze 0]

On the receipt of my notice of approval it says it's valid from 12/2/2010 to 04/1/2011

My medical is on the 21st of February. Will my interview for my K1 at the embassy need to be before the expiry date of the I-129f?

Have I left myself enough time? Since the embassy don't schedule interviews until they recieve medical results, I've no idea how fast they work. I have already sent my notice of applicant readiness telling them my medical exam date.

They will automatically extend the validity of the NOA2 if it will expire soon. The only thing you might want to do is have the petitioner make a new letter of intent dated closer to the interview to reaffirm their interest in pursuing the visa, bring that to the interview (it probably won't even be needed, but just to be safe). London knows the process takes awhile so they renew the application all of the time.
