There's no need to do either. An idle data connection doesn't draw a noticable amount of power over having it disconnected.
At the same time, the GPS isn't active unless a program is using it. It will hold a lock for about 30 seconds (customizable per-ROM?), after that it will go inactive. Give it a try next time you're driving, open up Google Maps and let it acquire a lock. Close it, and open it again immediately - it will still be locked.
Now close it and wait a minute. When you re-open it, it will have to acquire a lock again.
So, no drain then if the GPS isn't locked because it isn't active.
