Profile strengths and weaknesses


I'd love to get some advice from this forum on a few aspects of the application. Any help is greatly appreciated!:

1) What are the most important factors for an MFE program? GPA, GRE, WorkEx?
2) Does work experience at a Big 4 in Transfer Pricing help? What if the Work Ex is not completely correlated to FE?
3) How important is research? Do I NEED it or is it just something which is more helpful?
4) Any MFE programs that are particularly generous with scholarships?

Thank you for your help!
