Does anyone know roughly how much data should pass back and forth when using push email (IMAP-IDLE), for arguments sake, when the phone is idle and receives no email. Every know and again a 'heartbeat' occurs and I cant seem to find out roughly how big this is.
I left my phone with push email on all day and approx 50k was send and 40k received. This seems a bit much to me.
What do you all think?

That seems roughly correct.
Remember, there is an initial "handshake" of the connection itself and the email thats about 5 to 10 KB at least. Then it downloads the headers themselves.
then to maintaint the TCP connection, there is a "ping" of some sort.
If you work on the IMAP server with another application, that will also send regular status messages to your phone describing the changes made.
For example, if you are using another computer (via another connection) to access yoru IMAP server, and then delete and then purge the inbox, or even reading, or replying to an email via the other computer. This will cause update messages to be sent to the phone.
This can easily consume bandwith even when not sending and recieving any mail. so 50K is actually quite good!

Even though most of my emails are only about 2kb total and I'm only downloading the headers?
