Undergrad and grad college.What should I study?Finance/banking at undergrad and MBA at grad?

I am workin and wanted to study Finance(need not be MBA also)

Since i am workin i can do only part time study.Also i want the study period shld be short since i will be here only for a year
i want to study in a college so that i can make some friends too.Also i dont like online universities since it will not have a strong foundation and curriculum as other universities have.

I will be graduating in about a year with double major in accounting and finance, which will give me 150 credits to sit for the CPA. How should i handle the CPA. Should i study for it right after getting my degree, or should i look for a job first. And how long should i study for each part, will i be finished with my CPA within a year. I also want to get a MBA sometime in the future. Thanks in advance.
