How to make anti-aliased lines & edit brush size for Photoshop CS3's Pen Tool?

[Garamonde]

Well, when I use the brush, it's automatically AA'd, and I can change the size (I also found where the smoothing and other options are), but when I switch to the pen tool it doesn't transfer the settings from the brush tool (unless I'm misunderstanding how it works). I can stroke the path after I draw it, making it smooth, simulating pressure, etc. but I know it's possible to have it set to be AA'd as you draw and that's what I'm having trouble figuring out how to do. When the pen tool's active there aren't any settings on top or in the menus to edit those things like there is with the brush (the brush settings are all greyed out when I try to access them in pen tool mode so I can't do that).

Thanks anyway though!

EDIT: Wait, you can't change the size of the Pen Tool?
