Hello,
There's nothing special to watch for, just don't damage anything physically. What you need to do is only to unscrew everything, replace the battery and screw it all back as it was. Maybe only to watch that you don't unscrew some parts all the way, only as much as you need to release it, so you don't loose the screws. Believe me I know - I work in a factory that produces the whole electrical system for BMW 3 Series ;)
Anyway, here I found a detailed instruction with pictures:

How to jump off a BMW 325CI


The battery for your car is located in the trunk. There are jumper terminals located under the hood in the front of your car. There is a Red (+) terminal that is under a little black cover on the passenger side of the engine bay near the firewall. Right near that is a silver/gray bolt that is bolted to the frame of the car. This is the negative terminal.

Make sure both cars are and all accessories are off:
1) Connect the Postive cable to the dead battery
2) Connect the Positive cable to the good (BMW) terminal
3) Connect the Negative cable to the good (BMW) terminal
4) Connect the Negative cable to the dead battery
5) Start the BMW. (if you have 2 people then gently rev the engine)
6) Start the dead car.
7) Let both cars idle for a while before disconnecting any cables
8) Remove in the opposite order.

How to replace front brakes on 2004 BMW 325ci


If it's like most BMW brake rotors you don't remove the center nut to remove the rotor. You should see a slotted screw in the rotor a couple of inches out from the center. Remove it and the rotor comes off. Might have to tap rotor with a rubber mallet but it should come right off.
