What was wrong was it badly lit? If its badly a trick is to put it on sports mode for auto settings but on manual u have to keep playing with the shutter speed iso and aperture and do test shots at the location before your shoot starts is the best way because, setting up iso etc is only dependent upon lighting conditions, set your shutter to 125th and iso high until get good lighting, ill do a video on this soon

Also dont forget that on manual u gotta practice alot cause to subject keeps moving fast and your photos can turn out blurry cause of the movement so set your shutter speed high 125th minimum

yes

yes depends how far you are away in relation to plane photographyi dunno if 300mm is close enough depends what you shooting though, but its good enough for sports shots
