I'm at TUM and will start the second to last semester (OB, Peds, Geri) this fall (07). Getting accepted is the easy part, as noted above. From there, it's an uphill process. I won't lie to you, it's hard... but it's do-able and worth it... that's why we're here
As for how to best prepare... pay attention in A&P and when you get into the actual nursing program read, read, read!!! Find some people who would like to form a study group and study together and compare notes with each other. Also find people to practice check-offs with.
Clinicals aren't too bad as long as you have your paperwork done and you know your stuff (the "stuff" you learned in check-offs like how to take a B/P, give a bed bath, and then later on giving injections, starting an IV, etc). When I started, my class had 80-something. We now have 60-something. It's not easy, as I said before. But I think it's worth it and I wouldn't trade it for anything in the world
