How far away is the tournament? If it's near you're probably not advised to be rush-learning something. From Gambit may be a 'good' opening but if you mess it up because you don't know it well enough you could get into trouble. Stick to what you already know as perviously advised.
If it's a bit further away you might want to investigate some lines more deeply - but probably just remembering basic opening principles and applying them will see you through. As GP says, off-beat openings for a reason.
btw: you may be interested to know that in 25+ years of OTB chess I've faced the moves you give precisely twice in serious tournament play (with maybe a couple more if we included rapid play events).
Assuming my experience is in anyway representative you wouldn't want to be wasting too much time on these systems.
