I have a question... does it make any difference which colour space your photos are saved in? (yes, as you may tell from my other recent posts, I have "issues" with colour space)

Anyway... supposing the photos that come out of my camera are sRGB and I am editing in PSE6 as sRGB...and I merrily send it off to an online lab... am I selling myself short by using that colour space or should I be using something else? And are the prints likely to come back looking better if I do use something else?
