When they say this, what they mean is that colour-correcting is up to  
you, since they don't want to change the calibration on their workflow.

Depending on how you feel about multiple proofs (and how much they  
charge) this can be a valid way to work. (Generate a  .pdf, send out  
for a proof, tweak RGB original or [your] calibration settings based  
on proof, repeat).

Yes, placed image format / colour models will be preserved, so create  
in / convert to CMYK in advance.

Text / rules will be as specified, so specify all colours in CMYK ---  
please note that on-screen appearance will be approximated --- how  
close will depend on how well your monitor is calibrated. A good  
printer, for a large customer will usually be willing to do an on- 
site visit to calibrate your equipment and discuss this sort of thing.
