Once you get your buoyancy and trim sorted, I'd practice deploying a Delayed Surface Marker Buoy (DSMB, or "safety sausage"). A good skill to have anywhere, but especially important drift diving in places like Southeast Florida or Cozumel -- shoot the DSMB before your safety stop, and the boat should be waiting when you surface. There are many videos on YouTube, but I like this one as being brief and to the point (remember when you release it to have it out far enough that it doesn't snag on your snorkel or other gear):
P.S.: Just saw your new post. Yes, if you've got the itch now, you should fly to Florida or Mexico to do your check out dives.
