However, you still see those flights on united.com since United doesn't serve Key West and united.com will still try to get you to your destination (regardless of carrier). I've booked America West flights (pre-merger) on united.com many times (they always came out as paper tickets though).
You will be able to earn OnePass miles for the flights operated by Continental. You will not yet earn OnePass miles from UA or other Star Alliance flights.
Warreng has it correct.
I'm guessing that the only portion of your flights that are on CO are the EYW segments. Probably EYW<>TPA or EYW<>FLL. Other than that you're probably booked on some combination of UA and US flights. This is fairly typical when booking to EYW using UA's website.
I did pretty much the same thing earlier this year flying PHL-TPA-EYW. The TPA<>EYW legs were on Gulfstream (Continental Connection) and the PHL-TPA legs were on US. I earned UA miles for PHL-TPA (*A agreement) but nothing for TPA<>EYW.
One caution if you are traveling through TPA. With transfers to CO/CO Connection at TPA, all the CO/COX flights are in a different terminal from US and you must re-screen security going from one terminal to another. The booking engine allows short connections (25 minutes IIRC) at TPA which is not really practical with the required re-screening. I'd allow at least 40 minutes.
