Definitely ask each printer for their .joboptions file appropriate to the type of work you will submit. Colour is a roll of the dice unless you at least use the settings that the prepress department prefers for their particular software and press setup. Colour management via a Spyder or similar isn't worth a thing if your output file isn't right for that printer.

General rule: Always, always, always consult the printer about any job before you submit final art. Your print providers and your clients will thank you, and you'll sleep better at night.
