As you already know, a 335xi automatic is not ideally suited for HPDEs. If it were me I'd sell it and buy something more suitable for the track. That said, if you are intent on sticking with what you've got I'd consult Dinan and Turner Motorsport. My dealer had a CPO E93 335i with the Dinan Stage 3 software and it was very quick. In fact, I would have bought it had it not been a slushbox.
You'll need an oil cooler if your car doesn't have one. Dinan's cooler is excellent but pricey. As for ECU reflashes, COBB, Dinan, GIAC, and Turner all have their proponents. No one I know tracks an xi car so I can't speak to long term durability of either the transfer case(or the autobox for that matter).
Looking at the suspension, Dinan or H&R sport springs/Bilstein sports should work fine.
 
Finally, you may want to try a couple of schools before you dive into modifications as may well find that the "spirited dynamics" of a RWD car are something to be enjoyed rather than feared.
Please understand that I'm not saying that your xi is a bad car for the street. I just think that you'd be much happier in the long term with a car that is better suited for the track.

You make very valid observations and I will follow your advice. I have not played with RWD since my early 20s ....may be I am forgetting something there....(hopefully not a true sign of senility).
Thank you very much.

Well, like I said, try your car at an HPDE before you start modifying it. If you like the way it performs you may want to go ahead with your plans. If you don't enjoy it, I doubt modifying it will change your opinion.
The HPDE bug bit me bad, and it may get you too. It's a blast.
