How can I improve my profile for a MFE/PHD in Fin. Math?

Hello,

I left the labor force a year and a half ago as I was facing depression. I worked as a Market Analyst for a pharmaceutical branding company for 2 months before being let go as I wasn't a "good fit". Before that I worked as a Marketing Analyst for a rather large Insurance broker quoting High Net Worth PnC accounts and handling said accounts for 2 years.

I am a Hispanic- Male, 3.66 GPA. I got my Bachelors of Science in Economics from a State School. These were my grades:

Relevant Math/Stat/CS: Calc 1: A- Calc 2: A Calc 3: C+ Linear Algebra: A- Discrete Math 1: B+ Calculus-Based Probability: B+ Time Series Analysis: B Design of Experiments/ Analysis of Variance: A- Programming 1 (C++): A

Relevant Econ Classes: Intermediate Micro: A Intermediate Macro: A Econometrics: A Analysis of Economic Data: B+ Financial Markets and Monetary Policy: A Game Theory: B+ Business Organization and Market Structure: A-

Relevant Insurance: Risk Management and Insurance: C ( ouch, I took my lest semester and got lazy)

I have decided to go back to school this spring and take: Programming 2 (C++) Computer Organization 1 ( needed for Data Structures class in summer) Discrete Math 2 Numerical Analysis

And this in the Summer: Data Structures and Algorithms 1 Computer Organization 2 Diff Eqs. Study for and take the GRE

Assuming I ace the classes I plan on taking, and get 3 solid letters of rec. Would this be enough to get into a mid tier/low tier program with funding?
