(oops, how did I not see that last post?, oh well, I'll leave my post up anyway...)

If you're only going to pull and replace that cheap bottom bracket I'd just use a hammer and flatblade screwdriver on that BB lockring and adjustable cup. As for the fixed cup, 12" Crescent.

Heck, you might even consider it if you're going to repack and continue using the BB. Once you repack it, it should be good for many miles.

If you feel you'll be doing a lot of this type of work then go ahead and get a lockring tool at the very least. HCW-5.
