Hi. I'm a noob wrench and need some advice. I need to replace the BB on my '90ish Specialized Hardrock. (it has Shimano 200GS parts) I was going to order some tools, but I wanted to make sure I'm getting the right ones for the job. I have a workstand, and a pretty complete automotive toolkit but I have very few bike tools. Can you think of anything I will need besides:

Also (hard to tell for sure because I bought the bike used and cheap) I think it is missing the lockring from the non-drive side. Would this come with a new BB?

A search on the innerwebs showed that I need a square taper, 68mm shell, 113mm spindle, sealed cartridge BB. Any way to confirm this, and where can such info be found?

Thanks in advance for any help.
