It's up to you on whether to encrypt RTP payload only or the whole
RTP packet. From the source that you sent earlier, it looks like
you're encrypting the whole RTP packet. Which shouldn't be a problem
(for the stream), as long as the decryption can restore the original
RTP packet correctly.
No you don't need to encrypt RTCP if you don't want to, and whatever
you do to RTCP will not affect the RTP stream.
