Soo... anyone know what tool to use to remove this type of bottom bracket?

Park Tool BBT-22 or any other bike-tool maker's equivalent. Good tool to have, there's a lot of those BBs out there nowdays.

Here's where I'm confused:
"The BBT-22 is a shop quality tool for installing and removing ShimanoŽ and ISIS DriveŽ splined 20-tooth bottom bracket cups."

My bb cups have 16 teeth (4 sets of 4 teeth with gaps in-between).

That tool will still work, it's pretty much a de facto industry standard at this point.

Ok, thanks :)

btw, what's the difference between the bbt-22 and the bbt-22c?

Nevermind, found my answer on Park Tool's website. The only difference is the particular composite of metal used to manufacture the tool.

In Park Tool's nomenclature, the C designates it's on a retail display card that can be hung from display hooks.
