> #00 Philips and a swiss army knife and you're sorted.
ThinkPads use #1 JIS Phillips screws almost everywhere, with some #0 JIS apparently used for internal parts. (I haven't encountered any #0 myself, just #1.)
#00 is definitely too small. You may be able to get away with it, but it's much easier and less likely to damage the screw heads if you use the right size driver.
The "JIS" is Japanese Industrial Standard, a slight variation from ordinary Phillips.
Wiha screwdrivers are my favorite; I use a #1 Wiha for all my ThinkPad work.
