Hi everyone..I am wanting to attempt to take out the BB and clean and reinstall myself rather than take to the LBS. This will be my first "major" maintenance project. While I am scared I'll really mess something up, if it is not to complex a project I am wanting to attempt it. I have read the ParkTool site and have two manuals in front of me and it seems pretty straightforward.

I do need help though choosing the tools I will need. Currently I have a Shimano Tiagra crankset FC-4550 on a GT Series 3 (2010, I think) F100405665 or 201003172-3. First, since I don't have any tools except the normal household variety, what specific tool do I need to get the Cranks off and what BB tool do I need for whatever kind is there? I am thinking this will work...
