A visa obtained in advance will eliminate that potential problem. Doesn't always happen....but it does happen.
No.
Airline agents will almost always check for visas or VOA letters unless you are visa exempt. Separately they will sometimes check for onward tickets but this is completely unrelated to whether you are traveling on a visa, carry a VOA, or are visa exempt.
Checking for visas and checking for onward reservations are unrelated and independent of one another.
If you are visa exempt there is NO benefit in obtaining a visa.
