PhD Accounting - Wisdom Appreciated

Hello,

I'm currently working as a staff accountant in the tax department of a small to mid-sized public accounting firm. I'll presumably have my CPA license during the summer, and plan to make my next step from there. However, I haven't really decided what I want to do my life, but I came to the forum seeking more information about getting a PhD in accounting. Based on my research, it seems most reputable universities put research before teaching. Both interest me so I feel this would be a good career fit for myself. However, I do have some questions and would appreciate you evaluating my chances of getting into a good PhD program.

-3.73 GPA undergrad accounting from a well known Big Ten school
-3.47 GPA Macc program from the same school
-2 semesters being a teaching assistant for introductory accounting (taught classes with about 60 kids once a week and proctored exams)
-CPA license (soon)
-1-2 years public accounting experience (soon)
-Have been a good test taker my entire life, so I figure I can get 700+ on the GMAT
-Will most likely be able to get solid letters of recommendation from my former professors

Questions:
-Which type of programs do you anticipate me having a reasonable shoot of getting into?
-What is a realistic starting salary for someone in my position? A range would be fine, but I've just seen too many different ranges of numbers to accurate assess reality (this forum seems like a good place to ask)
-Is being a PhD student for 5 years worth the end result?
-How difficult is achieving tenure at most, well-known universities? Do most schools even give tenure anymore?

Any insight would be greatly appreciated.

Thanks.
