You basically just remove the old cups, and install the new cartridge. You don't need any other parts...just the proper tools, and make sure you get the right width spindle...

You can't convert it. It's a remove, toss and replace.

Also, check that your cranks are compatible with the bottom bracket spindle. I'd assume your current cranks are "square taper". Splined bottom brackets are common these days, and are not compatible with square taper.

It is reverse threaded. Make sure you are trying to turn it clockwise to remove it.

A lot of folks find it easiest to clamp the fixed cup flats in a bench vice, then turn the frame.
