Cinelli Gazzetta bottom bracket issues

Hi everyone. I have a Cinelli Gazzetta 2018. I have increasing noises coming from the bottom bracket but I don't have the tools or the spare parts at the moment to do anything about it. The frame is with a Bottom Bracket Standard: BSA and Shell Width: 68 mm and supposedly the crank set is Lasco 46T-170mm. Can anyone help me out with the tools and replacement parts that I need to get?
