Knowing what you need to remove what and in what order is the most difficult part in taking apart a laptop. Having that guide linked above will make things considerably easier.
If you want to try overclocking, go for a 400MHz Pentium M 1.5-1.7GHz as those are my picks to be successful. As with overclocking, it's never guaranteed. Unlike overclocking desktops, you can't simply up the voltage. With the pin mod, it's either a 33% increase or none at all. No intermediatary steps.
Now, judging by how you have responded to this thread, I would forgo overclocking and just go straight for a 533MHz FSB Pentium M chip. It's hard to say exactly which one since prices can vary greatly. Just use your best judgement and find the highest clocked Pentium M chip at a reasonable price.
But remember, a Core Solo, Core Duo or Core 2 Duo will not work!!!
