I've rewired Reason into Logic a while back, but it was only doing MIDI from Logic to Reason, and Audio from Reason to Logic - which is what you already know how to do.
I'm not sure if it's actually possible to route MIDI from Reason back into Logic using ReWire? If it's not you could try using IAC busses? If you can set the MIDI Out of Reason to an IAC bus, then you'll see it present in Logic, you'll just have to create a MIDI track and record on that.
