Which tool for this Bottom Bracket? (Pictures)

I am attempting to overhaul my 1982 Trek 614's bottom bracket. I have gotten the crank arms and the lockring off. I bought a Park HCW-11 tool for removing the bottom bracket but it appears I need a different tool. There are no slots to fit the tool into. I have attached pictures - what tool will work to remove this bottom bracket? Do I need to remove the drive-side as well if Im only overhauling it?

HCW-4 will fit the fixed cup and MIGHT be spaced correctly for the adjustable cup. Else a pin spanner like the SPA-1.

You can probably spin the adj. cup out with a couple Phillips screw drivers

Something like this

http://www.amazon.com/Park-Tool-HCW-...dp/B000AOA2G8; pin spanner end for adjustable cups and box end for fixed cup.

You should be able to leave the fixed cup installed. You can clean, inspect, and regrease it from the other side.

Make sure it's torqued down tight (LH threads!) while you've got the cranks off.
