What are the do's and don'ts as far as modifying the WRX, I believe you can't get rid of all the cats as this will mess up some sensors. Also is the Dawes device suitable for the 02 and is it safe? What is the best or most suitable induction kit? Sorry for the questions but it just seems that they are not as easily tuneable as the old model.

you can get rid of all the cats, all you need is the cel fix. and after full decat i would suggest uprated piping, then full remap

Scoobydoo69 is correct. I would advise fitting a set of gauges first though (turbo pressure, fuel / air mix etc) - just to avoid any potential problems. Gauges should also warn you before a problem becomes serious!
