Since you're applying to an academic program and not an MBA, it's hard to say, because the score expectations of academic programs can be very different from those of MBA programs (and people on this forum aren't likely to know about specific non-MBA programs). I know some professors who use GMAT and GRE scores for admission decisions to graduate programs in pure economics, and they almost don't care at all about Verbal scores, but they want to see extremely high Quant scores (so someone with a Q45/V45 would stand a worse chance of admission than someone with a Q50/V25). But that won't be true everywhere -- each program will have its own criteria.
If you want to be sure of how to proceed, the best thing to do would be to try to learn about the specific expectations of the programs you're interested in. That's not always easy to do for academic programs though. Your Q48 is very good, but if you had reason to think you could score higher (so if, say, you had Q49+ scores on official diagnostics, or if you got the Q48 without doing much preparation), there's some chance that would be helpful. It's only if a program cares about your overall score out of 800 (which may be the case) that raising your Verbal would matter -- your V37 is also very strong, and should be more than good enough for a Finance Masters. As for scholarships, they all have their own criteria too, and you'd want to look into the details of the scholarships that interest you; for some, standardized test scores are an important factor, and for others, standardized test scores are irrelevant. Good luck!
