Bottom bracket repair

NB: Originally posted elsewhere on the Global Riders Network and appears via syndication.

I was riding at Stromlo and I noticed a squeaking sound coming from the bottom bracket. I want to repair/replace any parts myself. Do I need any special tools to do this job, and if so, what tools? (I don't want to take it to a bike shop because the last time I went, they forgot to put the axle back in the wheel :/)

In the vain effort of trying to improve my mechanical skills I am slowly rebuilding a bike. In this I have just put in a new set of XT cranks and bottom bracket – seemed easy enough. Although I did have to tap the crank with a wooden mallet to pop it through the BB. Not a big wack, just a gentle tap – is this usual? It seemed to be just getting the end to clear through – this was also the case when not on the bike so I am happy things are square.

Bearing replacement

One set of the bearings in both my headset (Ritchey Pro Semi-Integrated Press Fit) and in my bottom bracket (Shimano XT Hollowtech II) are starting to make crunching noises - so I guess both got dirt and water in and corroded the bearing or the race. I have tried cleaning and lubing and that does seem to help for a few rides but I suspect the bearings are gone.
