A lockring wrench like a Park Tool HCW-5 or Hozan C-205 would be an appropriate tool for the lockring. When assembling and/or adjusting the bottom bracket, you’ll also need something to turn/hold the bearing cup. The cup will have some type of tool interface machined into it — maybe a slot, a hex head, or a series of holes for a pin spanner like a Park Tool SPA-1.

Yes, and that diameter & threading identify the unit as a common English-threaded bottom bracket.
