To point to the answer for recordingpitch-bend and modulation at the same time:

With the CC-controllers it is fairly easy as you can midi map those to specific controller and thus record to automation.
With pitch bend, this is currently a different story in Renoise.
I hope that will change one day, at least that we get the ability to map the pitch-bend to specific controllers as well.
