I know I want to go into Auditing.... CPA or CIA??? Which one should I start with?

I would suggest you go for the CPA. You cannot make a career out of external auditing at a public accounting firm without it. Also if you went into internal audit a CPA would look really good. One caveat though is a CPA is not required by public accounting firms for internal audit so if you know 100% you want internal audit you could potentially forego the time and stress related to sitting for the CPA. However my personal opinion is to go far in the accounting world and especially audit of any kind a CPA is an important tool to have (and as I said in external audit it's a requirement if you want to stay in it). Any certifications beyond that would be dependent on which path you wanted to take (cia, cisa, cfe, etc). FYI I just left a big 4 accounting firm as a senior manager in external audit so that is where my info is coming from. Hope this helps.
