1] Lots of patience-Mark anyting you disconnect and tag it. By the time your are done, your going to have a lot of bolts laying around.
2] Replace with anything but stock gears- they are terrrible. Roller gears are nice, but not necessary for every day use.
3] Read and understand the cam sensor setting procedure. If you don't, you'll be posting here right after you are done because you can't get your car started.
4] I personnally would replace the crank sensor at that time.
5] be careful when you remove the balancer. It's ez to damage the interuptor ring.
6] Replace the fuel filter a that time as well
7] Same for the belt
8] Tighten the balancer to the correct torque fittings, or see #3 above.
Good luck!
