Best prep for SA in exotic trading

First of all: THANK YOU! This is an amazing site, and you guys have been extremely helpful :) Thanks to you I have been able to secure a summer internship in 2012 with one of the biggest BB's in London. I will be on a rotational program in FICC S&T. I would love to land an offer on a trading desk, preferably in emerging markets exotics, FX- or rates exotics.

I would be very grateful if you have any advice on how I should spend the next 6 months preparing? I'm an undergraduate in Math and Econ from a non-target European country. I have done the mandatory courses in real analysis, linear algebra, measure theory, macro- and micro-economics and econometrics. Now I'm having grad courses in credit risk modeling and arbitrage theory in continuous time (the Tomas Björk book).

1) Do you have any suggestions for good books on options-trading in rates or FX space? I.e. something on the lines of Hull or Sheldon Natenberg?
2) Any recommendations for level of computer literacy? VBA or Matlab for a trading desk, etc.? I have heard that a lot of the pricing is done via Monte Carlo simulations. Is this true or can someone confirm this?
3) Good publications on EMEA emerging markets for fx and rates? E.g. what drives Turkish, Polish, Russian and South African rates?

Thanks ;)
