Quantitative finance jobs for a pure mathematician

I'm a pure mathematician with a Ph.D. and I'm currently a visiting professor at a large state university. However, I'm looking to switch gears and get into the quantitative finance field. The problem is that I don't know anything at all about finance. I know that there are companies such as D. E. Shaw that hire mathematicians that don't have financial experience; what other companies should I look at? Is there any general advice you'd give someone in my position? Also, I have my Ph.D. from a well-regarded state school, but I'm not an Ivy-leaguer; does that put me at a disadvantage?

Allocating my assets between mutual funds in my IRA account

I have four mutual funds in my IRA account - a Total Market index fund, a Small-cap index fund, an International stock index fund, and a Bond index fund, and I'm trying to figure out how to allocate my assets between them. I've read a little bit about "Modern Portfolio Theory" and the "Efficient Frontier", but I'm struggling to understand some of the math. So, is there a simple way I can test whether a particular allocation is on the efficient frontier? Or, see all the possible allocations on the efficient frontier and choose between them? How do I figure this out? Ideally, I'd love to see a simple enough formula that, given the mean and standard deviation (and maybe correlation matrix), of my four funds, would tell me what allocation is on the efficient frontier. Or, some type of online tool, or an Excel spreadsheet or something. [more inside]

Question re: statistics and financial modelling

Question about semi-sophisticated statistics and financial modeling - lets say you have N asset classes - each class has a mean rate of return and a standard deviation of returns. Also, assume you hold a portfolio comprised entirely of these N asset-classes, in certain proportions. How do you determine the probability that the portfolio might produce the a certain rate of return over P periods?
